Parotid gland tumours are rare in dogs. In this report, a 7-year-old, female, spayed bearded collie was presented for subacute onset of neurological signs. A meningoencephalitis unknown origin affecting the cerebellum diagnosed 10 months before had successfully been treated with prednisolone and mycophenolate mofetil. Head CT MRI showed right-sided retropharyngeal mass invading caudal fossa com...

INTRODUCTION Solitary fibrous tumor is associated with serosal surfaces. Location in the salivary glands is extremely unusual. Extrathoracic tumors have an excellent prognosis associated with their benign clinical behavior. We report an aggressive and recurrent case of this tumor. We review the clinical presentation, inmunohistochemical profiles and therapeutic approaches. CASE REPORT A 73-ye...

A 17-year-old male presented with a painless swelling in the right parotid region of 2 years duration. The swelling was progressively increasing in size. On examination there was a round, firm, smooth-surfaced and non-tender swelling in the right infra-auricular region. CT scan revealed a smooth well-defined mass with a lobulated surface and homogeneous soft tissue density. Clinical differentia...

Introduction. Angiofollicular lymph node hyperplasia (Castleman's disease) is a nonmalignant lymphoproliferative disorder that generally involves the lymph nodes of young adults, most commonly in the mediastinum. Rarely, Castleman's disease may present in the parotid gland. The disease can be further classified into unicentric or multicentric forms, with considerable differences in presentation...

Chronic sclerosing sialadenitis (CSS) (Kuttner's tumor) is a benign fibroinflammatory condition most commonly affecting the submandibular gland. It presents as hard mass that mimics salivary gland neoplasms. We report an unusual presentation of Kuttner's tumor parotid in order to raise awareness this rare and underreported entity.

A 32-year-old man with a ten-year history of bilateral cervical adenopathy, parotid gland swelling, and a posterior mediastinal mass, presented with headaches. A CAT scan of the head revealed a suprasellar mass. Craniotomy and biopsy of this lesion led to a diagnosis of sinus histiocytosis.

Rhinosporidiosis is a benign chronic granulomatous infection caused by Rhinosporidiosis seeberi (R. seeberi). Rhinosporidiosis is endemic in South Asia, notably in Southern India and Sri Lanka. The common sites of involvement are the nose and nasopharynx followed by ocular tissue. Rhinosporidiosis is also known to involve many rare sites and may become disseminated to ocular in generalized form...
