RESUMO
Leukemia cutis is the infiltration by neoplastic leukocytes or their precursors into the epidermis, dermis or the subcutis resulting in clinically identifiable cutaneous lesions. The diagnosis is of great value in cases where leukemia cutis aids in the diagnosis of leukemia. This has a poor prognosis and strongly correlates with additional signs of extramedullary involvement. A 27-year-old male patient, known case of AML-M3, presented with cutaneous nodules on both lower limb, which on biopsy proved to be leukemic deposits. Immunohistochemistry confirmed the diagnosis and the patient was discharged with advice to continue chemotherapy.
RESUMO
Hyalinizing clear cell carcinoma (HCCC) of tongue is a rare neoplasm originating from minor salivary glands. We present a case of HCCC involving the base of tongue, in a 73-year-old male, clinically diagnosed as fibroma. Laser excison of the mass was done. Histopathological examination showed an infiltrating lesion composed predominantly of clear clear. The differential diagnosis included other salivary gland lesions having a clear cell component and metastatic clear cell renal carcinoma. lmmunohistochemistry was useful in ruling out these lesions exhibiting clear cell component from clear cell carcinoma. imaging studies revealed no lesion in either kidney. Since, HCCC has a better prognosis and the adequate treatment is wide excision, it needs to be differentiated from other carcinomas with clear cells. No further therapy was given to the patient. One year after the surgery, the patient is symptom free without local recurrence and on regular follow up.
