The adenomatoid tumor is the most frequent paratesticular tumor. It is a benign tumor, which in women is mainly found in the uterus and the fallopian tubes, while in men it is most frequently found in the epididymis. These lesions may also affect the testicular albuginea, the spermatic cord and, in exceptional cases, the testicular parenchyma, of which there are only 4 published cases, the ejac...

The bening tumors of paratesticular tissues are uncommon and their frequency rating is as follows:adenomatoid tumor,leiomyoma and papilliferous cystadenoma.this paper reports two new cases of epididymal adenomatoid tumor in 43 and 25 years old males presented with testicular pain and a mass in their testes.diagnosis was achieved through physical examination and sonography with confirmed patholo...

Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin, constituting only 3% of all odontogenic tumors. AOT is characterized histologically by the formation of duct-like structures with amyloid-like deposits. An 18-year-old male presented with right chek swelling. CT scan revealed well-defined expansile heterogeneous mass with central hypodensity. Patient underwent excis...

Adenomatoid tumor (AT) is a rare benign mesothelial neoplasm of the paratesticular region and mainly involves the epididymis. A definitive diagnosis of this tumor is important because it is difficult to differentiate clinically and radiologically from other intrascrotal pathology and malignancy. Histopathological examination along with immunohistochemistry is diagnostic and conclusive for diagn...

BACKGROUND Adenomatoid tumor is one of the most common histological subtypes of paratesticular cancer arising from the epididymis. In very rare cases, these tumors appear as intratesticular lesions originating in the tunica albuginea, representing a diagnostic challenge. CASE PRESENTATION We present a case of a 51-year-old man with a small (0.9 cm) hyperechoic lesion of the left testicle mimi...

Adenomatoid tumor is an uncommon benign mesothelial neoplasm, usually localized in the epididymis. It is the most common paratesticular tumor of middle-aged patients (average age of clinical presentation: 36 years). However, these tumors in pediatric and pubertal patients are extremely rare. Due to their rarity, we present a case of adenomatoid tumor of the tail of the epididymis in a 16-year-o...

Adenomatoid tumor of the ovary is rare, and so are collision tumors in this location. The most common histological combination of ovarian collision tumors is the coexistence of mature cystic teratoma with ovarian cystadenoma or cystadenocarcinoma. Presented herein is a rare case of ovarian adenomatoid tumor found incidentally and coexisting with mature cystic teratoma. A 44-year-old woman prese...
