RESUMEN
Benign tumors involving peripheral nerves of the upper extremity are uncommon. The swelling may be misdiagnosed as other soft tissue neoplasm like lipoma, ganglion or lymph node. Schwannomas also known as neurilemmoma usually originate from Schwann cells located in the peripheral nerve sheaths. They account for about 5% of all the benign soft-tissue neoplasms in the adults and 19% of the tumors occur in upper extremities. Schwannomas generally presented as an asymptomatic mass causing discomfort. With the increasing size of the tumor pain, numbness, and fatigue may occur. We report a case of schwannoma on forearm which was clinically misdiagnosed as foreign body granuloma and was excised. Diagnosis was made on histopathology. Diagnosing the peripheral nerve schwannomas can be challenging clinically. Hence, a detailed clinical, radiological and histopathological evaluation is essential. Peripheral nerve schwannoma is rare and observation of a single patient can add to our understanding this rare disease.
RESUMEN
Abstract Filariasis is a major public health problem in tropical countries like India, China, Indonesia, Africa and the Far East. Aspiration cytology often helps in demonstration of microfilaria and its various forms, from uncommon diverse areas and in unusual clinical presentations like subcutaneous swelling caused by W.bancrofti in our cases. In our cases various forms of W.bancrofti were seen on cytology. Microfilria being most common form seen on cytology, adult worm, coiled forms (embryos) and ova seen less often. FNAC can be helpful in diagnosis of symptomatic as well as asymptomatic cases of lymphatic filariasis. During cytological evaluation of tissue fluids and aspirate from lesions of any part of the body, possibility of filariasis must be kept in mind as a possible differential diagnosis, particularly in endemic areas. This will help to give appropriate therapy to asymptomatic patients.
