A 51-year-old hypertensive and diabetic male patient, admitted due to acute kidney injury on top of chronic kidney disease, was referred to the dermatology service. He presented with a 3-month history of multiple discrete pruritic papules with keratotic plugs over the extensor aspects of the bilateral upper and lower extremities, initially managed as a case of scabies infestation but medications given provided no relief. Histopathologic analysis of a skin biopsy revealed findings of acquired perforating collagenosis. Resolution of lesions and pruritus were noted after starting on a topical corticosteroid ointment on the lesions, as well as hemodialysis to address the renal failure. Subsequent consults showed no recurrences and only a minor sequela of post-inflammatory hyperpigmentation.

Intravascular Papillary Endothelial Hyperplasia (IPEH) is a rare benign vascular lesion of the skin and subcutaneous tissues that results from the proliferation of endothelial cells within a blood vessel. In this article, we present the case of an IPEH mimicking a Sister Mary Joseph Nodule on the umbilicus of a 53-year old female patient with ovarian cancer. A diagnostic workup was performed with a computerized tomography of abdominal cavity and pelvis showing an expansive cystic tumor formation with probable ovarian origin. Two separate histopathologic readings were done on the cutaneous lesion which revealed contradicting findings of benign versus malignant tumors. Immunohistochemical stains done showed that the lesion was positive for ERG and negative for epithelial differentiation markers. No surgical intervention was done at the time of consultation as a cutaneous metastasis was primarily considered initially. It is crucial to rule out a diagnosis of Sister Mary Joseph nodule, especially in a background of ovarian carcinoma as it may mimic vascular lesions occurring on the umbilicus. Immunohistochemical staining is a significant tool to precisely diagnose such lesions so that it is neither inadequately nor aggressively managed.

Introduction: Lupus panniculitis (LP) is an unusual type of cutaneous lupus erythematosus (CLE) wherein the cutaneous inflam- matory reaction involves primarily the deeper dermis and subcutaneous fat. It is characterized by the appearance of recurrent, mostly asymptomatic, firm, nodules or plaques, involving the face, upper limbs, and buttocks. Case report: In our case, a 30-year-old female presented with a non-tender, non-movable nodule on the left breast, 6 weeks prior to her admission. She had fever, chills, and joint pains. The patient later developed hyperpigmented plaques on the infra- clavicular area, and left flank extending to the abdomen. Urinalysis showed proteinuria, and RBC cast. She also had leukopenia, and anemia on CBC. Chest computerized tomography (CT) scan revealed a heterogeneously enhancing soft tissue mass in the base of the neck at the right infraclavicular region with malignant features. ANA titer was normal, while skin biopsy on two sites and direct immunofluorescence studies were compatible with lupus panniculitis. She was managed as a case of systemic lupus erythematosus (SLE) using a combination of hydroxychloroquine, and oral corticosteroids, which afforded temporary relief of symptoms. The patient however was lost to follow-up and opted for alternative medicine, and subsequently succumbed to the complications of SLE. Conclusion This case highlights the importance of a carefully made assessment after an accurate clinicopathological cor- relation was done. This case also emphasizes that although LP if associated with SLE may signify a milder condition, judicious monitoring and follow-up must still be undertaken since management is based on the disease activity.

Introduction: Angiosarcoma is a rare head and neck sarcoma of vascular endothelial cell origin. We report a case of angiosar- coma in an elderly male, and the multidisciplinary approach employed in his treatment. Case report: A 79-year-old male presented with a 4-month history of a rapidly enlarging black, soft, immovable tumor surround- ed by bruise-like patches over the right temporoparietal scalp. There was associated pruritus and bleeding when scratched. Dermoscopy showed bluish black crusts over the tumor, and surrounding violaceous patches. Wedge biopsy revealed a dermis with irregular vascular spaces infiltrating dermis, lined by atypical endothelial cells. Immunohistochemistry of the atypical in- filtrative cells was positive for CD31. These findings were consistent with angiosarcoma. The patient underwent wide excision with a rotational flap and split thickness skin graft. Postoperatively, the patient was referred to Oncology for adjuvant radiation therapy. Conclusion Even with treatment, the prognosis of angiosarcoma remains poor due to its aggressive nature, with a 5-year sur- vival rate ranging from 10-54%. However, early detection of the disease may increase patient survival rates. This rare case shows the importance of maintaining a high level of suspicion for lesions that have an atypical presentation to prevent delays in man- agement and improve patient outcomes.

Introduction: Nevus lipomatosus superficialis is a rare benign hamartomatous skin lesion. It is classified into 2 types: solitary and multiple. Lesions consist of multiple, flesh-colored or yellow papules and/or nodules in a segmental pattern, with a linear, zosteriform, or along the lines of skin folds distribution. Surfaces are smooth, but may also have verrucous or cerebri-form appearance. Pathogenesis is unknown, but there is speculation that precursor cells around dermal blood vessels give rise to mature fat cells in a mosaic pattern. Incidence is presently unknown, but this is the first reported case in this institution. Histopathology reveals presence of aggregates of mature adipose tissue among the collagen bundles of the dermis. Case Summary: DF is a 14-year-old, Filipino, female, who consulted due to multiple, pedun-culated, soft papules over the right lower back, and extending to the right flank, with a clustered arrangement. There was no history of trauma or manipulation, nor was there pain, pruri-tus, or other associated symptoms. Past medical, family, and social history were non-contributory. Initial impression was acrochordon. Excision biopsy revealed mature adipose tissue in the dermis, which is diagnostic for nevus lipomatosus superficialis. Serial excision was done. Conclusion Excision is the treatment of choice. Other treatment options that can be ex-ploredare COz laser, cryotherapy, and intralesional injection of phosphatidylcholine, which yield promising results recommended by other studies. Dermatopathology plays a vital role in the diagnosis of this condition. A high index of suspicion, a good clinical eye, and dermatopa-thologic analysis are essential tools in clinching the diagnosis.
