“…There are only few, outdated, reports of testicular leiomyomas in few fish species (Budd, Schroder, & Dukes, 1975; Herman & Landolt, 1975), and none have been found in the testicles of aquaculture broodstock fish. Leiomyosarcoma is a malignant tumour originating in smooth muscles (Singaravel, Gopalakrishnan, Raja, Vijayakumar, & Asrafuzzaman, 2017) and has rarely been diagnosed in fish (Harshbarger, 2001). Leiomyosarcoma has been reported in African lungfish, Protopterus aethiopicus (Hubbard & Fletcher, 1985), and Atlantic salmon, Salmo salar (Bowser et al., 2012).…”

Testicular leiomyomas and gonadal dysfunctions are not commonly reported in teleost and particularly in broodstock fish. In the present work, a testicular leiomyoma related to an unusual case of spermatogenic failure syndrome, in a broodstock seabass coming from an Italian aquaculture farm, is reported. At gross pathology, the circumscribed neoplasia showed several white nodular masses, originating from the gonad, deforming the anatomo‐physiological shape. From light microscopy, the presence of neoplastic tissue islands with spindle cells with a whirling pattern and the low presence of connective tissue were evident and originated from smooth muscle cells. Seminiferous tubules showed severe azoospermia with the absence of sperm cells even closer to the neoplastic area. Immunohistochemical analysis was positive for alpha‐SMA, desmin and vimentin but negative for S‐100, confirming a diagnosis of leiomyoma. This is the first report of spermatogenic failure syndrome associated with a testicular leiomyoma in fish from broodstock. More efforts should be made in studying broodstock fish pathologies related to fish maintenance and hormonal treatments that could economically affect aquaculture production.

“…Recently, however, we have reported a high incidence of tumours in both cultured and captured fish in India, such as Mugil cephalus (Jithendran, Natarajan, Pramoda, & Thiagarajan, ; Singaravel, Gopalakrishnan, Raja, Vijayakumar, & Asrafuzzaman, ), Sardinella longiceps (Gopalakrishnan et al., ; Sinduja, Vijayakumar, & Gopalakrishnan, ; Singaravel et al. , ; Singaravel, Gopalakrishnan, Vijayakumar, Raja, & Asrafuzzaman, ,b), Sphyraena barracuda (Gopalakrishnan et al., ), Chanos chanos (Ananda Raja, Panigrahi, & Kumar, ), Puntius sarana (Sahoo, Mohanty, Das, Mahapatra, & Saha, ), Sphyraena jello (Singaravel, Gopalakrishnan, Raja, Vijayakumar, & Asrafuzzaman, ,b; Vijayakumar, Gopalakrishnan, Raja, & Sinduja, ), Lates calcarifer (Vijayakumar, Raja, Singaravel, & Gopalakrishnan, ), Arius jella (Singaravel, Gopalakrishnan, Vijayakumar, & Raja, ) and Rastrelliger kanagurta (Singaravel, Gopalakrishnan, & Raja, ). Tumours in goldlined seabream ( R. sarba ) have not previously been seen, and to our knowledge, this is the first such report.…”
