“…This complexity was more evident in our second case, because besides glands, prostatic stroma and fetal urothelium, we also found other typically male structures, such as Cowper's glands and cavernous bodies. Such structures have been reported in the literature close to the prostatic glands by McLachlin and Srigley 4 and by Nogales et al 6 The male urogenital sinus derives from fusion of the uro-rectal septum with the terminal mesonephric ducts, close to the origin of the ureters. From this structure, at 30-35 days of gestational age, the urethra, prostate and lower part of the Collision tumour of the pleura composed of small cell carcinoma and malignant mesothelioma Sir: In their recent paper Attanoos et al 1 report three cases in which mesothelioma was intimately admixed with another tumour type.…”

Interestingly, these leiomyomas frequently contained EGs. Intracytoplasmic EGs, appearing ultrastructurally as globular filamentous bodies, are a well-known feature of various neoplasms; the constituents of the type of filaments vary in different tumours: both cytokeratin and vimentin (rhabdoid tumours or rhabdoid cells in several malignancies), actin (infantile digital fibromatosis), or thin and thick myofilaments (rhabdomyoma, rhabdomyosarcoma). [3][4][5] The current study has shown that colorectal leiomyomas frequently contain intracytoplasmic EGs, which are mostly composed of a globular aggregation of desmin, intermingling with actin. To our knowledge, the presence of these globules in colorectal leiomyomas has not been previously reported in the literature. Moreover, we suggest that the presence of these EGs may be a useful marker for differentiating leiomyomas from reactive muscular thickening since our control study failed to reveal any EGs in non-neoplastic muscularis mucosae. These EGs mimicked skeinoid fibres 1,6 on light microscopy, although ultrastructural examination showed that this was not the case. The possible assessment of 'skeinoid' fibres should be carefully ruled out in differentiating leiomyoma from GIST on microscopic examination.

“…In addition, some of these reports described the presence of urothelium, Cowper's excretory ducts and glands, and a vascularized area with sinusoids surrounded by a fibromuscular wall of the cavernous type [3,6,7,8,9]. A case of prostatic adenocarcinoma in a mature cystic teratoma of the ovary has also been reported [3].…”

“…They form a functionally common group because they excrete liquid substances for slurring spermatozoons. Seminal vesicles in the male have no homologue in the Prostatic tissue has rarely been described in the female genital tract [1][2][3][4][5][6][7][8][9][10][11][12]. Most reports documented the occurrence of prostatic tissue as a component of teratoma; however, ectopic prostatic tissue has also been found in the uterine cervix and vagina [5], including a patient with adrenogenital syndrome [4].…”

Mature cystic teratoma of the ovary with male accessory sexual glands including seminal vesicles, prostatic tissue, and bulbo-urethral glands: a case report

We present an extremely rare case of a benign cystic ovarian teratoma with structures of male accessory sexual glands. The patient was a 30-year-old woman. A unilocular cystic tumor, measuring 5 cm in the largest diameter, was found in her right ovary and was removed. The teratoma contained epidermis, skin appendages, respiratory and intestinal epithelia, cartilage, muscle, and nervous and connective tissue. In addition to these histologically mature tissues, there were nodules with prostatic acini, prostate duct-like structures strongly positive for prostate-specific antigen and acid prostatic phosphatase, structures resembling Cowper's glands, and seminal vesicles surrounded by fibromuscular stroma. To our knowledge, this is the first case in the English literature describing seminal vesicles associated with prostatic tissue and bulbo-urethral glands in a mature ovarian teratoma.

We report here the case a 30-year-old parous, phenotypically normal, reproductive woman. She presented with mature teratoma of the ovary, which contained well formed, grossly visible prostatic gland with a central urothelium-lined duct resembling a urethra. Mature teratomas are characterized by the presence of tissues derived from the embryonic layers of ectoderm, mesoderm, or endodermal lineage. However, prostatic tissue is a very unusual component of teratomas. The rare existence of prostatic tissue in a mature teratoma can be explored through three feasible pathogenetic theories. These origins include teratomatous monodermal differentiation, developmental abnormality, or metaplasia. The coexistence of rare prostatic tissue with a rare central urethral duct in a mature teratoma makes this case a particularly intriguing one. To our knowledge, this is only the second case of ovarian mature teratoma containing a urethral duct in prostatic tissue in the literature.
