“…In 1 other case gross hematuria was directly attributable to the adrenal AT. 8 Clinico-radiologic preoperative and intraoperative diagnosis is challenging if not impossible, because of the rarity of these lesions in this specific location, their usual hormonal inactivity, and the lack of specific radiologic features. 13 As a consequence of that, AT-AG is often confused with other more common adrenal tumors and mostly diagnosed clinically as benign nonfunctioning adrenocortical tumors, lymphangioma, myelolipoma, and cysts of various types (Table 1).…”

“…Immunohistochemistry has been performed in 29 cases, always showing the usual immunohistochemical profile of mesothelial cells, including strong immunoreactivity for cytokeratin (pankeratin, high-molecular weight cytokeratin 5/6) and calretinin. Ultrastructural analysis has been used in 10 cases, 8,9,11,14,16,18,21,30 in all of which the classical microvilli of coelomic type were always observed, these being the substrate of the ''brush'' border some people were able to observe and depict even on hematoxylin and eosin stained slides in mesothelial derived tumors, including AT-AG. 10 In all cases the AT-AG was totally resected (either by laparoscopic or open surgery), except for 1 (case 34, Table 1) where the diagnosis was made on core biopsy and the lesion was left for follow-up.…”

Adenomatoid tumors (AT) are usually found in the genital tract of both sexes. They are very rarely located in extragenital sites, and are exceedingly rare in the adrenal. AT of the adrenal gland (AT-AG) are nonfunctioning, usually discovered incidentally and confused on imaging with other more common adrenal neoplasms. The overwhelming majority occur in males. Thirty-four cases have been reported so far, more often presenting grossly as solid tumors, rarely as solid with cystic areas, and 5 cases were almost entirely cystic. At histology they can be either circumscribed or locally infiltrative, and may pose diagnostic difficulties when the pathologist relies on morphology alone or is challenged on frozen section. On light microscopy the diagnosis may be very difficult if the tumor is rich in vacuolated cells, mimicking metastatic signet ring-cell adenocarcinoma. Immunophenotyping and/or electron microscopy are paramount in helping to ascertain their mesothelial lineage. Lymphangioma is the main histologic mimic of solid-cystic and cystic AT-AG, but lymphangioma is immunopositive for endothelial markers and negative for cytokeratins and mesothelial markers. Ultrastructural analysis has been performed in 10 published cases of AT-AG, in all of which the classical microvilli of coelomic type were always observed. In brief we report herein the sixth case of cystic lymphangioma-like AT, which was incidentally discovered during clinical follow-up in a 39-year-old man undergoing cancer staging and surveillance after surgery. The adrenal tumor was 5.5 cm in size and was fully investigated immunohistochemically and ultrastructurally. A complete review of the literature is also presented.

Adenomatoid tumors are rare benign neoplasms of the paratesticular region, most commonly occurring at the tail of the epididymis. We present a case of adenomatoid tumor in a 65 year old male, known case of prostatic adenocarcinoma, who presented in Urology OPD with painless swelling in testis. Bilateral orchidectomy was done with clinical suspicion of testicular carcinoma. On histopathology, diagnosis of adenomatoid tumor of epididymis was made. Due to its rarity, it is important for the physician and pathologist to be aware of this interesting entity in order to make a correct diagnosis.

“…The main cause for involvement of genital regions is unknown but it may also involve adrenals, lymph nodes, pancreas, mediastinum and pleura. [5][6][7][8] These tumours are usually located in the lower pole of the epididymis (tail) usually as a separate mass with a mean age of presentation between 30 to 40 years, however these tumors can affect any age and cases have been reported in children as well as geriatric age group. Though it can be bilateral but has propensity towards left side than the right side.…”
