Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare type of non-Hodgkin lymphoma characterized by subcutaneous nodules, indurated plaques, erythema, and cellular infiltrates in the subcutaneous fat. Biopsies show neoplastic cells expressing cytotoxic T-cell markers and displaying moderate cytologic atypia while sparing the dermis and epidermis and showing variable degrees of necrosis, hemorrhage, and inflammatory changes. We describe a pediatric case of SPTCL in a 6-year-old boy, presenting with an unusual targetoid plaque and systemic symptoms, who showed significant improvement on systemic immunosuppressants without chemotherapy.

A 9-month-old girl was evaluated for recurrent fevers, rash, and indurated plaques, with laboratories demonstrating hyperferritinemia, hypertriglyceridemia, and pancytopenia, concerning for hemophagocytic lymphohistiocytosis. Biopsy of thigh lesion ultimately demonstrated subcutaneous panniculitis-like T-cell lymphoma. In a rare neoplasm of cytotoxic T-cells, subcutaneous panniculitis-like T-cell lymphoma presents with subcutaneous nodules in all age groups including children.

Background: Cysticercosis, a parasitic infection caused by the larval stages of the pork tapeworm, Taenia solium, predominantly affects cerebral and ocular tissues. The subcutaneous manifestation of this disease is a relatively uncommon clinical occurrence. Previously very few or no cases of cysticercosis presenting as subcutaneous solitary painful swelling have been reported in the literature.

Introduction: Deep mycoses acquired by penetrating trauma to the skin can have varied and sometimes atypical morphological presentations resulting in diagnostic dilemmas and delay in treatment onset. Histopathology can be a useful tool in not only diagnosing but also differentiating various deep mycoses.
Aims And Objectives: To observe various morphological presentations and histopathological features of deep fungal infections.
Cutaneous Metastases of Signet-Ring Cell Gastric Carcinoma: A Case Report.

Article Synopsis
- Cutaneous metastases from gastric carcinoma, specifically signet-ring cell (SRC) type, are rare but can indicate advanced disease or recurrence and may present as asymptomatic skin nodules that are easily misdiagnosed.
- Diagnosis relies on histopathological examination and specific staining techniques to confirm SRC tumors, which tend to spread aggressively and are resistant to chemotherapy.
- The presence of skin metastases is associated with a poor prognosis and necessitates a collaborative approach among healthcare providers for early detection and better patient outcomes.
