The classical triad of abdominal pain, vomiting, and bloody stool is absent in chronic intussusception for more than 2 weeks. Here, we report a 6-year-old female with recurrent abdominal pain for 2 months. Ultrasonography of the abdomen revealed an ileocolic-type intussusception. The lesion accompanying the tight fibrous adhesion was treated by resection and ileocolic anastomosis. It was diagnosed as intussusception with diffuse large B-cell lymphoma. A high index of suspicion for abdominal pain in children should result in the correct diagnosis and appropriate management.

Groin lesions can be classified as neoplastic or non-neoplastic. Neoplastic lesions include lipoma, epidermoid cyst, angiomyofibroblastoma-like tumor, liposarcoma, and synovial sarcoma, as well as metastases from lymphoma, neuroendocrine carcinoma, and carcinomas of the lung, breast, urinary bladder, ovary, vulva, and colon. Non-neoplastic lesions include hernias, round ligament varices, endometriosis, Kimura disease, Castleman disease, hematoma, and inflammation. Because the clinical implications and therapeutic strategies for groin lesions vary depending on the cause, the ability to noninvasively differentiate among etiologies is very important. Although there is substantial overlap in ultrasonographic findings across various groin lesions, some ultrasonographic features, along with clinical characteristics, may suggest a specific diagnosis. Familiarity with the ultrasonographic and clinical features of various groin lesions facilitates accurate diagnosis and treatment.

Granulocytic sarcoma, also called chloroma or myeloblastoma, is an extramedullary invasive tumor composed of neoplastic myeloid cells. In this report, we describe a 43-year-old male patient with a collision tumor composed of an adenocarcinoma and a granulocytic sarcoma in the stomach. The coexistence of a granulocytic sarcoma and adenocarcinoma in the stomach has, to the best of our knowledge, not been reported in the literature. The diagnosis of granulocytic sarcoma is very difficult; especially in the absence of concurrent hematologic disease or in the uncommon setting of coexistence with another tumor. Cautious observation is needed when a finding of unusual atypical cells admixed with an adenocarcinoma in the stomach is confronted.

Autoimmune diseases are occasionally associated with other autoimmune diseases in the same patients. Graves disease has been associated with systemic rheumatic diseases including systemic lupus erythematosus (SLE). The diagnosis of Graves disease in patients with SLE is well known, especially in adults, but few case reports have involved children and adolescents. We report a 14-year-old female who presented with Graves disease, proteinuria, arthralgia, decreased complement, and positive antinuclear antibody and who was diagnosed with SLE. Renal biopsy revealed class IV lupus glomerulonephritis. These clinical, laboratory, and histological findings indicate that class IV lupus nephritis may be associated with Graves disease. This possibility should be borne in mind when following patients with Graves disease in order to avoid any delay in the diagnosis and treatment of serious systemic autoimmune diseases such as SLE.

Late recurrence over 10 years after surgery and endobronchial metastasis are some of the spe‑ cific biological behaviors of renal cell carcinoma (RCC). The current report describes a case of solitary endobronchial metastasis at a subsegmental bronchus that developed 20 years after curative nephrectomy for RCC. A 71‑year‑old male was admitted to our hospital for pneumonia.Chest radiography showed multifocal ill-defined nodular opacities in the right lower lung zone, suggesting pneumonia. Subsequent chest CT confirmed pneumonic infiltration in the right lung. However, a 4.3-cm, well-defined, elongated mass with a branching pattern was also iden‑ tified in the right lower lobe, and a right nephrectomy scar was detected on the covered upper abdomen. The patient had undergone right nephrectomy 20 years ago due to clear cell RCC. Af‑ ter right lower lobectomy, the postoperative pathological diagnosis was endobronchial meta‑ static clear cell RCC. Endobronchial metastasis should be considered in a patient with a history of RCC who presents with a suspected endobronchial tumor, even decades after curative surgery.

Purpose:
To report a case of solitary fibrous tumor of the orbit in a patient with changes in tumor size and contrast enhancement.Case summary: A 64-year-old male patient presented with dizziness, discomfort on eye movement, anosmia, and proptosis. Orbital computed tomography showed an enhancing mass in the right extraconal space, lateral to the medial rectus and inferior to the superior oblique muscle. The mass appeared to be a cavernous hemangioma and the patient was monitored for changes in mass size and eye movements. After 24 months of follow-up, the mass size and symptoms of right eyelid swelling, proptosis, and diplopia had increased. Excision and biopsy of the mass were performed under general anesthesia. The biopsy confirmed that the mass was a solitary fibrous tumor. The postoperative period was uneventful and no recurrence was observed at 6 months after surgery.
Conclusions
Solitary fibrous tumor is a soft tissue tumor that rarely occurs in the orbit, and should be considered in cases with an intraorbital mass accompanied by increased size and changes in contrast enhancement on imaging.

Purpose:
Polydeoxyribonucleotide (PDRN) is a substance known to suppress inflammation and accelerate wound healing. In this experiment, the effect of PDRN treatment on carbon tetrachloride (CCl4)-evoked acute liver injury (ALI) was investigated using mice.
Methods:
We analyzed the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and conducted hematoxylin and eosin staining in accompany with terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining. Western blot analysis was also conducted to assess the expressions of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, adenosine A2A receptor, Bcl-2-associated X protein (Bax), and B-cell lymphoma 2 (Bcl-2). The mice were received intraperitoneal injection of 10-mL/kg CCl4, 4 times, once every 2 days. The mice in the PDRN treatment groups received intraperitoneal injection of 200-μL distilled water comprising each concentration of PDRN for 7 days starting 1 day after first CCl4 injection.
Results:
ALT and AST concentrations in the serum were reduced and TNF-α, IL-1β, and IL-6 expressions were decreased by PDRN injection in CCl4-evoked ALI mice. PDRN injection suppressed Bax versus Bcl-2 ratio and reduced the percentage of TUNE-positive cells in CCl4-evoked ALI mice. PDRN injection overexpressed adenosine A2A receptor in CCl4-evoked ALI mice.
Conclusions
The therapeutic efficacy of PDRN also can be expected for CCl4-evoked acute urogenital injury in addition to ALI. The current research suggests that PDRN may be used for the therapeutic agent of CCl4-evoked ALI.
