title: Epithelioid sarcoma: a diagnostic challenge.
abstract: Epithelioid sarcoma is an uncommon slow-growing soft tissue malignancy, associated with a high incidence of local recurrence and metastasis. We report a 26-year-old male with epithelioid sarcoma on the right palm with a long history of over seven years, which was initially misdiagnosed as cutaneous tuberculosis and epithelioid hemangioendothelioma, as a result of which the treatment was delayed. No metastasis was found in our patient. The patient was referred to the oncology centre where he underwent wide excision of the lesion followed by radiotherapy. The review of the literature including clinical and histological differential diagnosis is presented as it mimics inflammatory, benign tumors as well as other malignant conditions.
