South Med J 68: 86-89. The pain was diffuse and severe over whole of the thumb and was even tender to light touch. One month hence, the patient had complete pain relief. This is a good example of the Pacinian corpuscle, a vibratory sensation receptor, with layers of connective tissue wrapped like an onion skin around a central nerve that isn't well seen without silver stain. Acta Orthop Belg 69: 74-76. (2020) Pacinian corpuscle neuroma: A rare case report with review of Literature. These receptors respond to pressure and vibration and can be up to 1 mm in diameter. See more. When pressure is applied to them they respond by sending signals to the central nervous system. The region between the ITB (or the … Pacinian corpuscles are colored red, and nerve elements are colored yellow. The outer layers are composed of flattened cells, collagen fibers and a lymph-like fluid. All of the visible masses were excised. The total mean number in the hand was 300 (192-424). Primary closure was performed. The symptoms of this disease are usually alleviated after complete resection.

The subcutaneous distribution and number of Pacinian corpuscles were studied in ten fresh cadaver hands. The clinical signs were very prominent. The corpuscle transmits mechanical stimuli through the connective tissue lamellae and fluid, exciting the nonmyelinated receptor axon in its core (Figure 1). Pathology 12: 231-235. Pacinian corpuscles are the capsulated endings of sensory neurons. Pacinian corpuscles are the largest sensory structures in the skin, so they are easy to find. J Hand Surg 23: 370-372. They are the largest mechanoreceptors in the body and are important to recognize as they may be mistaken for pathology. Postoperative period was good.

The afferent nerve ending at the centre is enveloped by multiple concentric layers of flattened cells and an external capsule of connective tissue. Foot Ankle Int 22: 342-344. In addition to a neuroma or glomus tumor, Pacinian corpuscle hyperplasia should be considered in the differential diagnosis of digital or palmar pain of unknown etiology. We frequently noted hyperintense nodules in the palms of patients on water-sensitive MRI sequences, but were unable to explain their etiology. Similar lesions have been described in other parts of the body as well. There was no history of previous pain. Br J Plast Surg 9: 230-231. It is a sensory end organ consisting of concentric layers or lamellae of connective tissue and ground substance surrounding a nerve ending. To provide microdissection and histological confirmation of normal Pacinian corpuscles prospectively identified using MRI in a cadaver model. They were found to cluster close to nerves and vessels at the metacarpophalangeal joints and the proximal phalanx.

The Pacinian corpuscle is a pressure receptor that responds to high-frequency vibratory stimuli. In human sensory reception: Nerve function. They are located in the subcutaneous tissue, deeper in interosseous membranes, and also mesenteries of the gut. Scale bar, 100 µm. Paccinian corpuscles These look like 'onion' bulbs, and are commonly found in the dermis and subcutaneous tissue. The histology, presenting features and associated conditions are discussed in detail.

Some of the long or thick images are likely to include two or three adjacent or overlapping corpuscles. The inner core cells form from Schwann cells extending from the nerve terminal. Pacinian corpuscles. The definitive diagnosis and treatment of this disease are possible if surgical resection is performed after careful consideration of differential diagnoses. Capsule of Pacinian corpuscle (histological slide) Displacement of the skin compresses the corpuscle and triggers an action potential in the nerve ending. Pacinian corpuscle neuroma is an uncommon lesion with a limited number of cases reported. Any dermatologist making a differential diagnosis of unexplained severe pain in the finger must take into account Pacinian neuroma, in addition to glomus tumor and other types of painful soft-tissue tumor. The corpuscle is fluid filled and essentially incompressible. (2000) A Pacinian hyperplasia of the foot. © 2020 Singh SK, et al. Pacinian corpuscles are encapsulated sensory receptors located in the deep layer of the dermis and in the hypodermis. A 32-year-old female patient presented to the Department of Orthopaedics with pain of right thumb since last 8 months. These receptors are lamellar vibration receptors that produce rapidly adapting responses. Those Pacinian corpuscles that are found within a joint or joint capsule convey information to the central nervous system regarding changes in the positioning of the joint. Pacinian corpuscles are mechanoreceptors found in man and other animals. This is a pacinian corpuscule. Scale bar, 100 µm. We present an interesting case of a woman with Pacinian corpuscle neuroma of the thumb. The Pacinian corpuscles are sensory preceptors that are found in many areas of the body, with their greatest density occurring in areas that are more sensitive to touch, such as the fingertips.

Based on the reports excision and biopsy of the lesion was planned. A cadaver study. In addition to a neuroma or glomus tumor, Pacinian corpuscle hyperplasia should be considered in the differential diagnosis of digital or palmar pain of unknown etiology. The excised mass was sent for histopathological examination. Pacinian corpuscle neuromas may be associated with other lesions such as glomus tumour, Dupuytren’s contracture, multiple Pacinian neuroma and arteriovenous anastomoses [14-16]. Pacinian corpuscle neuromas are rare, with only about few cases reported in the literature. Arch Esp Urol 53: 634-636.
