The subperiosteal type of chondroma of hand is reputedly rare. Four such cases are reported two in adolescents, one in a child and one in an adult. The chondroma being localized to the phalanges, its most frequent development site. In one patient multiple chondromata were present. The relevant literature and typical characters of these subperiosteal chondromata are reviewed. Radiological images show clearly outlined tumors due to peripheral calcification. Treatment is surgical by block excision through healthy bone, this avoiding recurrence.

Introduction: Enchondroma protuberans (EP), a rare form of enchondroma with exophytic growth, differs radiographically from classical enchondromas and can mimic osteochondroma, periosteal chondroma, or chondrosarcoma. Proper differentiation is crucial to avoid unnecessary radical resection, as EP requires intralesional curettage rather than the surgical removal typical for osteochondromas.

Article Synopsis
- - Tenosynovitis with psammomatous calcifications (TPC) is a rare, non-cancerous condition that often affects women and is thought to result from repetitive use or trauma, commonly appearing at sites like the hands, feet, and wrists.
- - In a study involving 18 new cases, most patients presented with painful masses, and imaging often showed benign characteristics, but many of these cases were misdiagnosed as more serious conditions like gout or tumors.
- - Follow-up on patients (mostly for around 30 months) showed no local recurrences after surgical removal, highlighting the necessity for greater awareness among medical professionals regarding TPC.

Article Synopsis
- Acral fibrochondromyxoid tumor (AFCMT) is a recently identified, likely benign tumor found in the hands and feet, characterized by distinct histological features and a specific genetic fusion (THBS1::ADGRF5).
- In a study of 37 cases, the tumors predominantly affected middle-aged individuals (median age 47) and displayed well-defined structures with vascularity and chondrocyte-like cells in a chondromyxoid environment.
- Immunohistochemical tests showed most tumors positive for CD34 and ERG but negative for S100 protein, indicating that AFCMT is a unique entity distinct from other similar tumors.
