An inguinal mass of about 2.5 cm in diameter was diagnosed as potentially tumorous inguinal testicle by ultrasound and fine-needle aspiration. Adrenal glands and prostate were ultrasonographically unremarkable. The surgically removed cryptorchid testicle contained a greyish tumour that was histologically composed of spindle-shaped cells with elongated nuclei, embedded in a fibro-vascular stroma. Up to two mitotic figures per high power field were noted. Additionally, an interstitial cell hyperplasia and marked reactive proliferation of a collagen-rich fibrous tissue were observed. Tumour cells were positive for \u03b1-smooth muscle actin, desmin, and occasionally vimentin and S-100, leading to the diagnosis of an intratesticular leiomyosarcoma. As an adrenal-associated endocrinopathy was excluded and a complete fur recovery was observed after removal of the cryptorchid testicle the alopecia was eventually due to hormones produced by the hyperplastic interstitial (Leydig) cells.<\/jats:p>","DOI":"10.15654\/tpk-131034","type":"journal-article","created":{"date-parts":[[2014,11,25]],"date-time":"2014-11-25T14:38:06Z","timestamp":1416926286000},"page":"406-410","source":"Crossref","is-referenced-by-count":8,"title":["Testicular leiomyosarcoma and marked alopecia in a cryptorchid ferret (Mustela putorius furo)"],"prefix":"10.15654","volume":"42","author":[{"given":"S.","family":"Ziege","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Wellh\u00f6ner","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Cichowski","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.","family":"Baumg\u00e4rtner","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Kammeyer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2018,1,8]]},"reference":[{"key":"10.15654\/TPK-131034-1","doi-asserted-by":"publisher","DOI":"10.1177\/104063879901100214"},{"key":"10.15654\/TPK-131034-2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0531.2009.01567.x"},{"key":"10.15654\/TPK-131034-3","first-page":"333","volume":"15","author":"Baumg\u00e4rtner","year":"1987","journal-title":"Tier\u00e4rztl Prax"},{"key":"10.15654\/TPK-131034-4","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9975(08)80217-4"},{"key":"10.15654\/TPK-131034-5","doi-asserted-by":"crossref","unstructured":"Bry-Gauillard H, Meduri G, Abirached F, Constancis E, Brailly S, Chanson P, Young J.
