Association of karyomegalic interstitial nephritis with focal segmental glomerulosclerosis.

Unlabelled: Karyomegalic interstitial nephritis (KIN), first described in 1974, is a rare form of chronic tubulointerstitial nephritis. It is defined by the presence of markedly enlarged, hyperchromatic nuclei with prominent nucleoli, mainly involving tubular epithelial cells of the kidney, accompanied by marked interstitial fibrosis. The disease presents as asymptomatic proteinuria, gradually progresses to chronic kidney disease and eventually leads to end-stage renal disease by 30-40 years.

Congenital thymoma.

Thymomas are a heterogeneous group of tumors arising from the epithelium of the thymus. They are categorized by the proportion of neoplastic epithelia to lymphocytes and by the degree of cytologic atypia. Thymomas constitute 0.

Benign multicystic peritoneal mesothelioma: literature review and update.

Benign multicystic peritoneal mesothelioma (BMPM) is a rare peritoneal tumor diagnosed predominantly in pre-menopausal women. Associated risk factors include endometriosis and pelvic inflammatory disease in women, and prior abdominal surgery in both genders. To date, the pathogenesis of this disease remains controversial with possible etiologies, including a neoplastic versus a reactive process.

Hyalinizing clear cell carcinoma of the soft palate: a review of literature review.

Hyalinizing clear cell carcinoma (HCCC), also known as clear cell carcinoma, not otherwise specified [CCC, (NOS)], is a rare minor salivary gland tumor characterized by proliferation of clear cells, organized in trabecular cords, or solid nests within loose to densely hyalinized stroma. It is considered a diagnosis of exclusion by the World Health Organization (WHO) because other salivary tumors may also have a clear cell component. Hence, there is a wide differential diagnosis.

A Case of 45,X/46,XY Mosaicism Presenting as Swyer Syndrome.

Background: Swyer syndrome is a difference of sex development that is typically associated with mutations in genes responsible for testicular development. It is speculated that some cases may result from cryptic 45,X/46,XY mosaicism leading to abnormal gonadal development. The presence or absence of a 45,X lineage is important for prognosis and management.
