Introduction Primary synovial sarcoma (SS) of the prostate is the rarest variety of prostate sarcoma. The first documented and confirmed case of SS of the prostate was published by Iwasaki et al in the year 1999; since then, only a few cases of primary SS of the prostate have been published in English literature.
Case Report We report a unique case of primary SS in a young patient who presented with acute urinary retention and underwent emergency suprapubic catheterization, and on evaluation was diagnosed with primary SS of the prostate. Patient was managed with radical cystoprostatectomy and resection of the anterior wall of rectum infiltrated by the tumor with bilateral pelvic lymph node dissection and adjuvant chemotherapy. Patient died after 2 months of surgery.
Conclusion Primary SS of the prostate is a rare disease and important clinical entity to be included in differential diagnosis of acute urinary retention in young patients. It is associated with high local recurrence and poor prognosis, which warrants multidisciplinary approach of treatment.
Primary sarcoma of the breast is a rare clinical entity with an incidence of less than 1% among cases of breast cancer. Primary osteosarcoma of the breast is a very rare disease that shares clinical features similar to metaplastic breast carcinoma. A 57-year-old female Dravidian patient presented with a breast lump. A needle biopsy was suggestive of carcinoma. However, the mammogram was suggestive of dense calcification lesion, which is unusual in carcinoma. She underwent breast conservation surgery with sentinel lymph node biopsy; final histopathology was suggestive of osteosarcoma of the breast. After a follow-up of 18 months, the patient is healthy and disease-free. Primary breast osteosarcoma has to be considered as one of the differential diagnoses to metaplastic carcinoma and warrants a different treatment approach. Whenever there is discordance in clinical features, imaging, and histology, thorough evaluation with the mammogram, immunohistochemistry, and PET scan helps to resolve the issue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
