Painful heterotopic pacinian corpuscle in the hand: a report of three cases.
ABSTRACT Severe pain in the finger caused by an abnormal Pacinian corpuscle is a rare condition. We have recently encountered three patients diagnosed with a heterotopic Pacinian corpuscle, based on histopathological findings. When making a differential diagnosis of unexplained severe pain in the finger, abnormal Pacinian corpuscles must be taken into account in addition to glomus tumour and other types of painful soft-tissue tumour.
Article: Benign cutaneous neural tumors[Show abstract] [Hide abstract]
ABSTRACT: Benign cutaneous neural neoplasms are one of the most frequent benign mesenchymal tumors in the skin. Because peripheral sheath nerve is composed of different cells, the tumors raised in these structures are varied and usually contain many of these cells. Most of these tumors are easy to diagnose, as usually present characteristic features well-recognized and express -specific immunohistochemical proteins. However, there are so many infrequent variants that many times require distinction from others spindle-cell tumors including melanoma. The tumors differ from one another by displaying a different proportion and arrangement of the various constituents of a peripheral nerve. In this article, we present the most characteristic clinical and histopathological features of many of these frequent benign cutaneous neural tumors including their uncommon variants.Seminars in Diagnostic Pathology 02/2013; 30(1):45-57.
