A 61-year-old woman presented with a 2-month history of non-painful left eye proptosis. Imaging studies showed a superotemporal mass in the left orbit with intracranial extension. Surgical excision of the orbitocranial mass was performed and histopathologic examination revealed metastatic papillary thyroid carcinoma. She subsequently underwent total thyroidectomy. Orbital metastasis from thyroid carcinoma is rare and can be the initial manifestation of occult disease in 63% of cases.

The COVID-19 pandemic has underscored the vital role of vaccination in mitigating widespread morbidity and mortality. Nevertheless, the global vaccination campaign has also brought to light rare but notable immune-mediated adverse events. Vaccination is inherently immune stimulatory, designed to provoke a robust immune response, and in rare instances, this heightened immune activity may unmask or trigger autoimmunity in genetically predisposed individuals. Proposed mechanisms include molecular mimicry, epitope spreading, and bystander activation, all of which can disrupt immune tolerance and initiate autoreactive responses. This case report explores a potential link between COVID-19 vaccination and the onset of dermatomyositis, adding to the growing body of literature examining the rare but important phenomenon of vaccine-associated autoimmunity.

High-Grade B-Cell Lymphoma (HGBCL) with gene rearrangements in MYC and BCL2 and/or BCL6 is an aggressive malignancy usually presenting in advanced stages. Current recommendations suggest the use of regimens more intensive than R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin, prednisone), which are based on retrospective studies and single-arm prospective trials that included patients who are mostly in the advanced stage, and did not receive consolidation radiotherapy.

The optimal approach and treatment of HGBCL, whether limited-stage (LS) or advanced-stage, remains to be determined. Here we describe the promising outcomes of three patients with LS and low IPI HGBCL with the use of R-CHOP as induction chemotherapy regimen, which was followed by consolidation radiotherapy.

Three women, 54-, 60-, and 64-years of age diagnosed to have HGBCL with MYC, and BCL2 and/or BCL6 rearrangements, with Ann Arbor stages I-IIE were included in this case series. All three patients had complete metabolic response to 6 cycles of R-CHOP and was subsequently treated with consolidation involved site radiotherapy (ISRT; total dose 30-36 Gy). Chemotherapy and radiotherapy were tolerated very well. All patients remain to be in remission, with the longest being at 23 months.

Outcomes of patients with HGBCL generally remain to be poor, but this may not be the case for patients with limited-stage disease and favorable clinicopathologic risk profile. Nevertheless, the treatment of HGBCL is currently evolving and more studies are needed to determine the ideal approach and preferred chemotherapy regimen. Also, more studies are needed to elucidate the potential role of consolidation radiotherapy in patients with limited-stage HGBCL to improve survival outcomes. Findings of this case series suggest that patients with LS HGBCL may still derive benefit from R-CHOP followed by consolidation ISRT, but prospective trials are needed to confirm this.

Intracranial lipomas are benign tumors that may occasionally be found in the suprasellar cistern while pituitary adenomas are far more common brain tumors. Pituitary adenomas may rarely coexist with other intracranial tumors in the sellar-suprasellar region. We share a unique case of a patient with coexisting non-functioning pituitary adenoma and sellar-suprasellar lipoma presenting with blurring of vision.

We report a 55-year-old male presenting with a two-year history of blurring of vision with findings of a 2.7 x 3.0 x 3.2 cm homogeneously enhancing lobulated isointense mass on the sellar-suprasellar region. Hormonal workups revealed low cortisol and mildly elevated prolactin. He initially underwent endonasal transsphenoidal excision of the tumor which revealed to be a lipoma on histopathology. Due to minimal improvement of vision from the subtotal excision, he underwent repeat surgery through the transcranial approach which in turn showed a pituitary adenoma.

The co-occurrence of two sellar-suprasellar tumors with different histology is rare, as most of the evidence is based on only a handful of case series. Intracranial lipomas result from persistence and abnormal differentiation of the meninx primitiva during the development of the subarachnoid cisterns. On the other hand, pituitary tumorigenesis is still largely unclear but appears to involve multiple tumor suppressor genes, oncogenes, cell cycle deregulation factors, and miRNAs. Given the differing pathogenesis of each tumor type, the coexistence may only be coincidental. The best surgical approach in this situation is unknown but the focus is on complete excision of the adenoma.

BACKGROUND AND OBJECTIVE

Type II Diabetes Mellitus remains a pressing public health concern among Filipino adults, particularly prevalent in urban households belonging to the middle to richest wealth population. As body composition influences glucose metabolism, understanding the potential of anthropometric parameters is vital in predicting fasting blood sugar. This study aims to generate and find the most appropriate model that can detect likelihood of elevated FBS using different anthropometric parameters.

The data set from 2018-2019, 2021 Expanded National Nutrition Survey of Department of Science and Technology - Food and Nutrition Research Institute, consisting of 14,655 adults aged 18–65 years from 33 highly urbanized cities (HUCs) was used in this study. While controlling for study variables, multiple logistic regression was used to determine significant predictors affecting the fasting blood sugar (FBS) status of these adults.

The above normal status of each anthropometric parameter, in the models for BMI (aOR=2.33; pCONCLUSION

There is no single anthropometric parameter that can truly discern the status of elevated FBS. However, it appears the use of waist circumference and waist-hip ratio have the potential to be an indicator especially in settings where the evaluation of the actual FBS of the individuals is not feasible. Future research suggests exploring possible interaction of BP, and FBS, diet quality and adequacy, and the effectiveness of having multiple anthropometric parameters in one model.

Epithelioid sarcoma is an uncommon mesenchymal malignancy which represents less than 1% of all sarcomas. Rarer still are reports of this tumor initially presenting in the vulva. We report a case of vulvar proximal-type epithelioid sarcoma.

A 52-year-old had a 5-month history of slowly growing papule on the right labia majora. Excision of the mass revealed a tumor composed of large polygonal cells with abundant eosinophilic cytoplasm. An immunohistochemistry panel revealed cytokeratin AE1/AE3 positivity only. She underwent radical vulvectomy with bilateral groin node dissection. The specimen revealed a cream tan, firm, fairly defined mass at the right vulva. Microscopic examination showed a sheet-like growth pattern of large pleomorphic epithelioid cells with large vesicular nuclei and prominent nucleoli. The tumor showed loss of INI1 nuclear expression and absence of CD34 staining. EMA was positive. The case was signed out as proximal-type epithelioid sarcoma of the right vulva. Two months post-operatively, the patient was given concurrent chemotherapy with 5 cycles of cisplatin 40 mg/m2 and 6600 centigray vulvar intensity-modulated radiotherapy. She had no evidence of disease for five months until repeat workup showed tumor recurrence in the perineum. She was subsequently given 6 cycles of gemcitabine 900 mg/m2 and gemcitabine 900 mg/m2 with docetaxel 100 mg/m2. Two months after, repeat workup showed persistent progressive disease in the vulva. She was subsequently given 4 cycles of doxorubicin 60 mg/m2 and is for repeat workup.

The immunohistomorphologic features of this tumor, in addition to its unusual location, present a diagnostic challenge. Clues to the diagnosis include an initial presentation as a soft tissue mass and microscopic features showing the presence of epithelioid to spindle cytomorphology with an infiltrative growth pattern. Immunohistochemistry studies revealing the loss of INI1 nuclear expression and expression of epithelial markers would ultimately establish the diagnosis of this rare clinical entity.

BACKGROUND

Melioidosis is an infectious disease caused by Burkholderia pseudomallei. It is endemic in the Philippines and is underreported. Of the reported cases, the most common comorbidity is diabetes mellitus. The increasing cases of antibiotic resistance and the relatively high mortality rate highlights the need for increased awareness among clinicians regarding this disease. We aim to report a case of Burkholderia pseudomallei resistant to trimethoprim/sulfamethoxazole (TMP-SMX), used in its eradication following initial intravenous therapy.

A 51-year-old male Filipino with poor health-seeking behavior came with generalized body weakness, weight loss, dysarthria, fever, cough, difficulty breathing, bloatedness, dysuria, joint pains, and bilateral lower extremity hyperpigmented macules for four months. He has diabetes mellitus and hypertension and is a mechanic by trade. Initial workups revealed hemoglobin A1c (HbA1c) of 14.7%, and urinalysis with bacteriuria. Imaging revealed bilateral pneumonia on chest xray, hepatosplenomegaly on whole abdomen ultrasound, and old cerebral infarcts on cranial computed tomography scan (CT scan). Empiric antibiotics for the impression of sepsis from community-acquired pneumonia and urinary tract infection were ertapenem and azithromycin. Upon isolation of Burkholderia pseudomallei from blood cultures, the team shifted to TMP-SMX and ceftazidime for initial therapy of melioidosis. Sensitivity showed resistance to TMP-SMX; hence the team revised the antimicrobials to four weeks of levofloxacin and ceftazidime. After eleven hospital days, the team sent the patient home, clinically improved. The team continued levofloxacin for eradication therapy for three months and the patient responded well.

Fever with multi-system involvement in a Filipino patient with diabetes mellitus with significant environmental risk factors, poor glycemic control, splenomegaly, and treatment failure with appropriate empiric antibiotic therapy should raise suspicion for melioidosis. It is paramount that antimicrobial resistance be detected and documented upon isolation of Burkholderia pseudomallei, given the high relapse rates and the need for a prolonged duration of treatment.

Renal cell carcinoma (RCC) is notorious for its propensity to metastasize even after a prolonged period of remission following nephrectomy. The metastatic spread can occur months or even years after initial treatment, which necessitates a heightened level of clinical awareness and vigilance in patients with a history of renal malignancy, particularly who present with new or unexplained nasal symptoms. Although RCC most commonly metastasize to the lungs, bones and liver, its involvement in the nasal cavity is exceedingly rare, posing significant diagnostic challenges due to the non-specific nature of symptoms. We describe a case of metastatic renal cell clear cell carcinoma presenting with recurrent epistaxis and unilateral nasal obstruction. Immunohistochemistry studies play a crucial role in confirming the diagnosis and ruling out potential differential diagnoses, along with a comprehensive clinical history of the patient.

Amyand’s hernia is a hernia where the appendix is within the inguinal hernial sac. It is often diagnosed by chance due its indeterminate clinical presentation. This case reports a 50-year-old Filipino male who presented with direct and rebound tenderness on the lower abdomen in the presence of a right inguinal bulge. CT scan showed an appendix coursing inferiorly into the pelvis, herniating through a 2 cm defect of the anterior abdominal muscle into the right inguinal region along with mesenteric fat. Laparoscopy confirmed acute appendicitis within an inguinal hernia (Amyand’s hernia Type 2). Diagnostic laparoscopy, appendectomy and primary repair of the right inguinal ring were performed. The patient had an unremarkable post-operative course and was discharged after 2 days. He was advised to undergo IPOM to prevent hernia recurrence. Laparoscopic management can be a safe option for cases of Amyand’s hernia.

BACKGROUND

Otomycosis, or fungal infection of the ear, is most commonly caused by Aspergillus, particularly of the Aspergillus niger species. On the other hand, pulmonary aspergilloma is a late manifestation of chronic cavitary pulmonary aspergillosis. Development of invasive aspergillosis is a possibility in immunocompromised patient but very rarely seen in immunocompetent persons. There have been no published reports in patients who initially presented as otomycosis and later development of pulmonary aspergilloma.

This case report presents 53-year-old Filipino immunocompetent female who was initially presented with ear discharges with diagnosed with otomycosis. She underwent modified radical mastoidectomy of the right ear with tympanoplasty type II. The patient then developed right facial nerve palsy due to erosion of the facial nerve canal. She was discharged with a final diagnosis of chronic suppurative otitis media with cholesteatoma; however, patient was not started on any anti-fungal medications. After fourteen months, the patient presented with episodes of hemoptysis and dyspnea and eventually re-admitted. Diagnostic work up was done with chest CT scan and serum galactomannan antigen test. She was diagnosed to have pulmonary aspergilloma. Patient was then started on long term anti-fungal therapy, instead of invasive surgical procedure. Repeat chest CT scan after six months showed a decrease in the size of the fungal ball.

This study illustrates the lung aspergilloma may happen with preceding history of invasive otic fungal infection even if there is no immunocompromised condition. It also emphasizes the importance of proper identification of infection etiology to ensure adequate control and prevent further opportunistic infection.
