Paraneoplastic pemphigus in a patient with T-cell lymphoma: a case report.

Introduction and importance: Paraneoplastic pemphigus (PNP) is an uncommon autoimmune mucocutaneous disease characterized by severe stomatitis, polymorphous skin eruptions, and the presence of underlying neoplasms. Unique histopathological features include suprabasal acantholysis and clefts with scattered necrotic keratinocytes. Case presentation: A 27-year-old female patient presented with a 3-month history of a painless swelling, approximately the size of a pea, on the left lateral aspect of her neck and axillary area. This swelling progressively increased in size and number. Additionally, she had reddish, itchy, raised skin lesions over her elbows bilaterally, which gradually spread to involve most of her body, including her lips, tongue, and buccal mucosa. These skin lesions were associated with difficulty swallowing both liquid and solid foods. A diagnostic test, including a biopsy, confirmed the diagnosis of PNP. Subsequently, the patient was managed with chemotherapy and other supportive measures, leading to improvement and eventual discharge. Clinical discussion: PNP is a rare blistering disorder associated with neoplasms, often presenting diagnostic and treatment challenges. Patients with PNP may develop a diverse range of lesions. It is crucial to promptly recognize and manage the underlying malignancy for improved patient outcomes. Conclusion: This case highlights the rare association between T-cell lymphoma and PNP. Clinicians should also remain vigilant for the possibility of PNP in lymphomas that are not of B-cell lineage.

Giant intraperitoneal non-pancreatic pseudocyst: a case report.

INTRODUCTION: Non-pancreatic pseudocysts are rare lesions that typically form from the omentum and mesentery. These cysts have a thick fibrotic wall made up of fibrous tissue and may show signs of calcifications and inflammatory changes. The fluid inside them can vary, ranging from hemorrhage and pus to serous or sometimes chylous content. In most cases, these cysts appear as a result of trauma, surgery, or infection. CASE PRESENTATION: A 35-year-old male patient from Ethiopia presented with swelling in his lower abdomen that had been present for 2 years. Initially, the swelling was small but gradually increased in size. The patient experienced frequent urination but no pain or difficulty during urination, urgency, intermittent urination, or blood in the urine. The swelling was initially painless but became painful 2 months prior to his presentation. Abdominal computed tomography scans revealed a well-defined, lobulated peritoneal lesion measuring 16 × 12 × 10 cm, consisting primarily of fluid-filled cysts with a thick, enhancing wall and septa. Additionally, there was a large, heterogeneous enhancing soft tissue component measuring 8 × 6 cm. As a result, the cystic mass was surgically removed in its entirety with partial removal of the bladder wall, and the patient was discharged in an improved condition. CONCLUSION: Primary non-pancreatic pseudocysts are extremely rare lesions that must be differentiated from other possible causes of cystic lesions within the peritoneal or retroperitoneal regions. Surgeons should be aware of the potential occurrence of these lesions, which may have an unknown origin.

Extraskeletal Ewing's sarcoma of the thigh with lung and bone metastasis: Case report.

INTRODUCTION AND IMPORTANCE: Extraskeletal Ewing's sarcoma is an uncommon tumor with a devastating prognosis and a very high mortality rate, particularly in metastatic forms, it primarily affects young people mainly in the 2nd to 4th decades of life. It can affect different parts of the body, without a particular clinical presentation which delays diagnosis. CASE PRESENTATION: 12-year-old male patient presented with swelling over the left proximal thigh of 7 months duration associated with pain and limping. On physical examination, he had about 20 × 15 cm firm, tender, and erythematous proximal left thigh swelling that is fixed to the structures with an overlying scar. CLINICAL DISCUSSION: Extra skeletal Ewing's sarcoma (EES) is a member of the Ewing Sarcoma Family of tumors. EES is a rare tumor with an incidence ranging from 0.1 to 0.4 per a million people. It presented with rapidly increasing swelling mainly over the soft tissue of the proximal thigh, pelvis, paravertebral region, chest wall, upper arm and shoulder. Age at presentation ranges 10 to 30 years with no gender preference. Imaging is crucial in the diagnosis, preoperative assessment, in staging and evaluation of treatment outcomes. Histopathology study is mandatory for the definitive diagnosis of EES among competitive differential diagnoses. The management of EES includes Surgery, chemotherapy and/or radiation therapy based on the stage of the disease. CONCLUSION: EES is a rare tumor but it should be in the differential diagnosis of adolescent patients presented with soft tissue mass/swelling.

Pediatric lymphatic leishmaniasis: a case report.

BACKGROUND: There are three main forms of leishmaniases: visceral (the most serious form because it is almost always fatal without treatment), cutaneous (the most common, usually causing skin ulcers), and mucocutaneous (affecting mouth, nose, and throat). Leishmaniasis is caused by protozoan parasites, which are transmitted by the bite of infected female phlebotomine sandflies. The disease affects some of the world's poorest people and is associated with malnutrition, population displacement, poor housing, a weak immune system, and lack of financial resources. An estimated 700,000 to 1 million new cases occur annually. Only a small fraction of those infected by parasites causing leishmaniasis will eventually develop the disease. We report a case of exclusive lymph node involvement in leishmaniasis, presenting as localized lymphadenopathies. The diagnosis of lymphatic leishmaniasis was confirmed by the presence of Leishmania donovani bodies in fine needle aspiration cytology, and positive anti-rK39 antibodies. The bone marrow aspiration was negative for Leishmania donovani bodies. Abdominal ultrasound was done and there was no organomegaly. Furthermore, localized lymphadenopathies may provide a diagnostic challenge by clinically mimicking a lymphoma or other causes of lymphadenopathy. Due to its rarity and its tendency to pose a clinical diagnostic challenge, we decided to report a case of lymphatic leishmaniasis. CASE PRESENTATION: A 12-year-old Amara male patient presented to the University of Gondar comprehensive specialized hospital, Northwestern Ethiopia, with six discrete right lateral cervical lymphadenopathies, the largest measuring 3 × 2 cm2, with no cutaneous lesion. Fine needle aspiration cytology confirmed the diagnosis of leishmaniasis in lymph node, and he was put on sodium stibogluconate (20 mg/kg body weight/day) and paromomycin (15 mg/kg body weight/day) injections, which are given intramuscularly for 17 days. Having completed his medication at the University of Gondar comprehensive specialized hospital, he had a smooth course and was discharged with appointment scheduled for follow-up after 3 months. CONCLUSION: In the clinical evaluation of a patient with isolated lymphadenopathies, leishmaniasis must be considered as a differential diagnosis in immunocompetent subjects in endemic areas for early diagnostic workup and management.
