Semicystic

Its dura periost had been partly destroyed by the tumor, which proved to be macroscopically semicystic and, microscopically, a chromophobe adenmoa.

Ultrasound shows a multiloculated semi-solid semicystic pelvic mass in a twelve year old girl with low back pain.

Other germ cell tumours are either solid or semicystic, and often malignant.

Imaging studies may show a cystic, semicystic, or solid lesion within the diploë of the bone or within the orbital soft tissues, with or without erosion of the adjacent bone [63].

Also Callichthyidae (Mattei et al. 1993), some Gobiidae (Mazzoldi et al. 2005) and Scorpaenidae (Muñoz et al. 2002) are characterized by a semicystic mode of spermiogenesis.

This is semicystic spermatogenesis first described by Mattei et al. (1993) in the Ophidion genus, and has rarely been reported in fish.

In semicystic spermatogenesis, Sertoli cells form, earlier than in other species, an epithelial lining of the spermatogenic tubules.

In fishes with semicystic spermatogenesis, round spermatids complete spermiogenesis while in a free state in the tubular lumen.
