RESUMEN
Schwannoma is a benign nerve sheath tumor that arises from Schwann cells of the peripheral nerve sheath with uncertain etiology. It is well-encapsulated and a slow-growing tumor. Approximately 25-48% of cases are seen in the head and neck region. Schwannoma of the oral cavity has an approximate incidence of 1%. Tongue base Schwannoma is a rare entity. It can affect all age groups and typically presents as a painless lump. However, when it grows larger than 3 cm, it may produce dysphagia, pain, or discomfort and change in the quality of voice. Hence, Schwannoma should be considered as one of the differential diagnoses of exophytic mass of the tongue. We report a rare case of Schwannoma of the base of the tongue in a 26-year-old male who presented with a complaint of lump, along with a review of the literature published in the last 64 years.
RESUMEN
Rhinosporidiosis is a chronic granulomatous disease caused by Rhinosporidium seeberi commonly affecting nasal mucosa, conjunctiva, and urethra. Subcutaneous tumor nodule presentation is rare and often mimics as sarcoma. Such tumoral rhinosporidiosis has been reported rarely. This report describes a 60-year male who presented with a solitary, firm, nontender swelling in posterior aspect of right leg with an ulcer and mimicking clinically as soft tissue sarcoma. Histopathology was diagnostic. Surgical excision was found to be useful.
