Primary undifferentiated embryonal sarcoma of the liver mistaken for hydatid disease

Primary undifferentiated embryonal sarcoma of the liver is a rare tumor with a peak incidence between the ages of 6 and 10 years. We report a case of a primary hepatic undifferentiated embryonal sarcoma arising in a 21-year-old male mistaken for hydatid disease of the liver. The rapid recurrence of this tumor along the site of attempted percutaneous drainage illustrates some important management points regarding this malignancy

Pulmonary Embolism in a Sarcoidosis Patient Double Heterozygous for Methylenetetrahydrofolate Reductase Gene Polymorphisms and Factor V Leiden and Homozygous for the D-Allele of Angiotensin Converting Enzyme Gene

Sarcoidosis is a multisystem granulomatous disease of unknown etiology and pathogenesis. It presents in patients younger than 40 years of age. The lungs are the most commonly affected organ. Till the present day, there is no single specific test that will accurately diagnose sarcoidosis; as a result, the diagnosis of sarcoidosis relies on a combination of clinical, radiologic, and histologic findings. Patients with sarcoidosis have been found to have an increased risk of pulmonary embolism compared to the normal population. MTHFR and factor V Leiden mutations have been reported to increase the risk of thrombosis in patients. We hereby present a case of a middle aged man with sarcoidosis who developed a right main pulmonary embolism and was found to be double heterozygous for methylenetetrahydrofolate reductase gene polymorphisms and factor V Leiden and homozygous for the D-allele of the angiotensin converting enzyme gene

Simultaneous occurrence of a CD30 positive/ALK-negative high grade T-cell lymphoma and plasma cell myeloma: Report of a case

Simultaneous occurrences of T-cell and B-cell neoplasms are rare, and etiological relationships between these two malignancies are poorly understood. We report the case of a 76-year-old man who presented with hypercalcemia, multiple skin nodular lesions, fatigue, episodic fever, and night sweats. PET/CT scan showed diffuse skin and subcutaneous fat plane active lesions, supra- and infra- diaphragmatic active lymph nodes, liver and spleen involvement, bone marrow infiltration, and nonspecific bilateral lung nodules. A skin biopsy showed a high grade CD30-positive/ALK-negative T-cell lymphoma. A bone marrow biopsy showed involvement by the same neoplastic cells. Additionally, a monoclonal lambda restricted plasma cell population (15% of marrow elements) was identified, which, in view of an IgA lambda spike in the serum, was consistent with plasma cell myeloma. To the best of our knowledge, this case is the first reported case of a plasma cell neoplasm associated with an aggressive CD30-positive ALK-negative systemic T-cell lymphoma with skin involvement. Reporting such cases is important as it adds to the pool of rare cases of concomitant T-cell neoplasms and plasma cell myelomas, and might help in determining an etiological relationship, if any, between these two hematological malignancies

Successful treatment of hydroxyurea-associated chronic leg ulcers associated with squamous cell carcinoma

Hydroxyurea (HU) is an antineoplastic drug used in the treatment of chronic myeloproliferative neoplasms (MPNs). HU is associated with cutaneous adverse effects, whereas severe complications such as leg ulcers and non-melanoma skin cancers (NMSCs) are rare and only observed after long-term treatment. We herein report a patient with essential thrombocythemia (ET) treated chronically with HU, and who developed refractory bilateral leg ulcers complicated by squamous cell carcinoma (SCC) over both heels. The patient was successfully managed by multiple debridement stages and skin grafting surgeries. Keywords: Essential thrombocythemia, Hydroxyurea, Squamous cell carcinom
