Adrenal adenomatoid tumor (AT) is a recently recognized disease with marked male predominance. Herein is presented a case of adrenal AT incidentally found in a 30-year-old man and results of immunohistochemical examination of the tumor. The left adrenal gland, weighing 17 g, contained a mass
Adenomatoid tumors (ATs) are uncommon benign mesothelial tumors with a predilection for the genital tract. We reviewed 47 ATs diagnosed at our institutions during 10-year period. Thirty tumors (64%) originated in the female (21 uterine, 8 tubal, and 1 ovarian) and 17 (36%) in the male (9 epididymal
The differential diagnosis between peritoneal mesotheliomas and serous carcinomas involving the peritoneum may be difficult, but it can be facilitated by the use of immunohistochemistry. To determine whether estrogen receptors (ER) or progesterone receptors (PR) may have any value as
Multiple subperitoneal nodules were produced in the abdominal cavities of guinea pigs treated with various doses of estradiol benzoate for 3 months. Gland-like structures with intervening fibrous stroma were observed in 20% of these nodules. These gland-like structures resembled adenomatoid tumors,
Glandlike structures with intervening fibrous stroma were observed in about 20% of subperitoneal nodules produced in the abdominal cavities of guinea pigs treated with various doses of estradiol benzoate (E) for 3 months. These glandlike structures were composed of cells resembling mesothelium,
Sixty cases of uterine adenomatoid tumors (ATs) are reported. All except four were incidental findings in hysterectomy specimens, three of these being discovered preoperatively as large multicystic tumors. ATs were classified into two distinctive macroscopic patterns: small, solid tumors and large,
Immunohistochemical studies of adenomatoid tumor (AT) are rare in the English literature. The author reports herein immunoprofile of AT of the female genital organs. The materials are 4 cases of AT of the uterus and 1 case of AT of the fallopian tube. The ages of the patients were 37, 41, 43, 45,
We describe a primary skin neoplasm located in the left chest wall that closely resembled adenomatoid tumor of male and female genital tract. It occurred in a 52-year-old woman who had undergone a left quadrantectomy with regional lymphadenectomy for invasive ductal carcinoma of the breast 7 years
A 44-year-old man presented with painless right scrotal swelling of 2 years duration. A cystic tumor strictly attached to the head of the epididymis was surgically resected. The pathologic examination revealed a unilocular cyst with a thin fibrous capsule, lined by ciliated cubical or cylindrical
Wolffian adnexal tumor (WAT) is a rare neoplasm believed to originate from wolffian remnants on the basis of its location in areas where these remnants are abundant. To study its histogenesis, the immunoprofile of 25 WATs was compared with that of 10 cervical and vaginal mesonephric remnants and 12
BACKGROUND
Primary cutaneous cribriform carcinoma (PCCC) is a rare and under-recognized variant of sweat gland carcinoma, characterized by anastomosing tubules and solid nests producing a sieve-like appearance.
METHODS
Six cases of PCCC were clinically, histopathologically and immunophenotypically
