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.

ABSTRACT: This paper describes a multiscale analytical model of the lamellar structure and the biomechanical response of the Pacinian Corpuscle (PC). In order to analyze the contribution of the PC lamellar structure for detecting high-frequency vibrotactile (VT) stimuli covering 10 Hz to a few kHz, the model response is studied against trapezoidal and sinusoidal stimuli. The model identifies a few generalizable features of the lamellar structure which makes it scalable for different sizes of PC with different number of lamellae. The model describes the mechanical signal conditioning of the lamellar structure in terms of a recursive transfer-function, termed as the Compression-Transmittance-Transfer-Function (CTTF). The analytical results show that with the increase of the PC layer index above 15, the PC inner core (IC) relaxes within 1 ms against step compression of the outermost layer. This model also considers the mass of each PC layer to investigate its effect on the biomechanical response of the lamellar structure. The interlamellar spacing and its biomechanical properties along with the model response are validated with experimental data in the literature. The proposed model can be used for simulating a network of PCs considering their diversity for analyzing the high-frequency VT sensitivity of the human skin.IEEE Transactions on Haptics 11/2014; 8(1):31-42.
