Giant lipoma in the hand: A case report.

Rationale: Although lipomas are the most common benign form of soft tissue tumor in the body, giant lipomas of the hand, defined as >5 cm in diameter, are extremely rare.

Patient Concerns: A 49-year-old man presented with a soft and fixed lump in the left hypothenar area. The mass was not tender, but it was associated with symptoms of tingling sensation and paresthesia in the left ring and little fingers that had lasted for 4 years.

Post-Traumatic Peripheral Giant Osteoma in the Frontal Bone.

Osteomas are benign, slow-growing tumors that most frequently occur in the craniomaxillofacial region. These tumors are mostly asymptomatic and are generally found incidentally. A giant osteoma is generally considered to be greater than 30 mm in diameter or 110 g in weight.

Subcutaneous Sarcoidosis Occurring in Both Chin and Toe.

Sarcoidosis is a systemic inflammatory disease characterized by non-caseating granulomas of unknown origin. Of the fewer than 6% of sarcoidosis cases that occur in subcutaneous tissue, most occur on the face or forearm, but rarely in the toe. A 33-year-old man was admitted to our institute with a 2-cm mass on his chin and a 0.

Cervicofacial Flap: Can We Save Patient's Sideburns?

Background: The conventional cervicofacial flap may cause the aesthetic problem of sideburns with a mismatched shape and arrangement. We developed a modified method with the goals of minimizing the destruction of the shape and arrangement of the sideburns and minimizing complications in comparison with the conventional method.

Methods: The incision line was designed to descend just in front of the sideburns, without passing through them, and then to ascend with the sideburns posteriorly when a cervicofacial flap is performed, unlike the conventional method.

Enhancement of BSA Binding on Au Surfaces by calix[4]bisazacrown Monolayer.

Effective investigation of biomolecular structure and function with chip-basedmodern instruments often requires reliable and steady attachment of designatedbiomolecules on substrate. Here, we investigated the formation of self-assembled monolayer(SAM) with a new calix[4]arene derivative containing bisazacrown ether at the lower rim(calix[4]bisazacrown) where ammonium moieties of proteins can mainly be interacted with.Immobilization process of protein using bovine serum albumin (BSA) on the Au surfacemodified with calix[4]bisazacrown monolyer as an artificial linker system was monitored bysurface plasmon resonance (SPR) technique.
