- BACKGROUND
Recent reports have indicated that renal cell carcinoma (RCC) with rhabdoid features follows an aggressive clinical course. We investigated the prognostic significance and nature of the rhabdoid component.
METHODS
We retrospectively analyzed the incidence and clinicopathologic characteristics of RCC with rhabdoid features in 174 radical nephrectomy cases. The specimens were examined histologically and immunohistochemically.
RESULTS
Twelve of the 174 RCC cases (6.9%) showed rhabdoid features. Histologically, all the tumors with rhabdoid features were of the clear cell type. The presence of rhabdoid features was significantly associated with higher Fuhrman's nuclear grade and higher pathologic tumor stage at presentation. Among the 12 patients who showed the rhabdoid component, nine (75%) developed metastasis and seven (58.3%) died of disease-related causes. The presence of rhabdoid features was independently associated with metastasis and disease-related mortality. The rhabdoid cells were positive for vimentin; variably positive for pan-cytokeratin, epithelial membrane antigen, and CD10; and negative for cytokeratin 7, smooth muscle actin, desmin, E-cadherin, and c-Kit. No case showed loss of integrase interactor-1; one was p53 positive, and five were insulin-like growth factor mRNA binding protein 3 positive. The Ki-67 labeling index was 1-25% (mean, 5.5%).
CONCLUSIONS
The rhabdoid component is an independent prognostic factor for metastasis of RCC; therefore, identification of this component is critical.

Abstract
PDF
- A cutaneous keratocyst is very rare and is ordinarily associated with nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome. NBCCS is a rare autosomal-dominant disorder that results from the mutation in the patched homologue 1 (PTCH1) gene located on chromosome 9q22.3, with high penetrance and variable expressivity. NBCCS demonstrates multisystem manifestations such as multiple basal cell carcinomas in early age, jaw cysts and pits of the hands and feet. Cutaneous keratocysts are characteristically lined by festooned keratinized squamous epithelium with parakeratosis. The cystic wall contains neither granular cell layer nor skin appendages. To the best of our knowledge, only two cases of cutaneous keratocysts not associated with NBCCS have been reported to date. We report one another case of a histologically confirmed cutaneous keratocyst in a 50-year-old female without a family history and clinical features of NBCCS.

Abstract
PDF
- Brucellosis is a zoonosis caused by several species of Brucella. Brucellosis is usually an acute or sub-acute febrile illness that histologically develops granulomatous inflammation. Brucella prostatitis is a very rare complication and is usually accompanied by epididymo-orchitis. We now report a case of histologically proven granulomatous prostatitis due to Brucella without clinical evidence of epididymo-orchitis. A 61-year-old farmer presented with myalgia, low back pain, and fever. A needle biopsy of the prostate was performed due to symptoms of urinary frequency and high prostate specific antigen levels (17.3 ng/mL). Histologically, the prostate showed granulomatous inflammation without caseous necrosis.
Polymerase chain reaction (PCR) studies of blood and prostatic tissue for Brucella were positive, while a PCR study for Mycobacterium tuberculosis was negative. The patient was treated with doxycycline and rifampin. A possibility of Brucella prostatitis should be considered in the differential diagnosis of granulomatous prostatitis or prostatitis of unknown origin associated with or without epididymo-orchitis.
