Cytology as a rapid tool in diagnosing tuberculosis of the parotid gland: A case series with a review of the literature.

Tubercular infection of the parotid gland often confuses clinicians, it being a rare entity even in an endemic area. Its similarity in presentation with that of parotid neoplasms, nonspecific symptoms, low incidence and non-contributory radiological findings often leads to its misdiagnosis as parotid neoplasm, which in the due course results in parotidectomy. Therefore, FNAC of parotid swelling is helpful to avoid unnecessary surgery and patient discomfort. We report four cases of FNAC of parotid swelling with suspicion of neoplasm/inflammatory lesion and were diagnosed as tuberculosis of the parotid gland. They were advised antitubercular drugs for 6 months and followed up. These case are reported not just to highlight that parotid is a rare site for tuberculosis, but also to ascertain that FNAC can be an easy and fast diagnostic modality for confirmation of tubercular parotitis rather than going through the long way of resection and confirmation on histopathology.

Schwannoma of the Scrotum: Case Report and Review of the Literature

Schwannomas are benign nerve sheath tumors composed of Schwann cells, which normally produce the insulating myelin sheath covering the peripheral nerves. Common locations include the head, neck, mediastinum, and retroperitoneum. These tumors are usually asymptomatic until they become large and compress the surrounding tissues. Most schwannomas occur during the third and fourth decades of life, with an equal gender distribution. We present the case of a schwannoma that originated in the scrotum.

Sarcomatoid renal cell carcinoma.

Sarcomatoid renal cell carcinoma (SRCC) is an aggressive tumor variant thought to arise predominantly from differentiation of clear cell carcinoma. A few reports of SRCC associated with non-clear cell tumors led to the presumption that SRCC may arise from any renal cell carcinoma, although direct evidence of this is lacking. We report a case of a 70-year-old male patient, who presented with acute left upper quadrant abdominal pain and was diagnosed to have SRCC after pathological examination. The patient is on high dose interleukin (IL-2)-based immunotherapy and is apparently free of disease six months after surgery.
