Literature reports of hyperostosis are often misleading and have been confused with osteomas, a pathological condition. Hyperostotic bones are known to occur only in bony fishes of the class Actinopterygii, within at least 16 orders, 35 families, 89 genera, and 153 species. They are present almost exclusively in marine fishes and exceptionally in a few extinct freshwater species known from hypersaline environments and one extant cichlid.

Purpose: The osteologic anatomy of the orbit is still a field of intense research, particularly as far as vascular channels are concerned. Among them, ethmoidal foraminas (EFs) are certainly those that have more clinical importance and indeed have been deeply investigated. Unfortunately, the vast production of articles, far from clarifying their anatomy, generated a certain degree of confusion.

Pleomorphic adenomas (PAs) are benign tumors of the salivary glands. Rarely, they arise in the sinonasal cavity, presenting as well-defined, homogeneous soft tissue masses, causing expansive bony changes. The significance of PAs is the possibility of giving rise to malignant carcinoma - "carcinoma ex-pleomorphic adenoma" (CXPA).

Fibrocartilaginous mesenchymoma (FM) is a rare bone tumor mimicking other fibrocartilaginous lesions on imaging and histologically. Hence, it is difficult to diagnose this entity especially on small biopsies. In this article, we report a case of FM mimicking desmoplastic fibroma on biopsy.

Background: The resident's ridge is an arthroscopic landmark that is consistent with the anterior border of the anterior cruciate ligament (ACL) femoral attachment. The identification of the landmark allows for accurate graft placement.
Case Report: We report a case of a 30-year athletic individual with an ACL-deficient knee, who had an abnormally large resident's ridge, abutting the midsubstance of the torn ACL; the residual femoral attachment was behind the ridge.
