The clinical signs were very prominent. Pacinian corpuscle in a lymph node Pacinian corpuscle in a lymph node Aydin, Özgür 2006-08-01 00:00:00 Sensory receptors make up a network of body‐wide sensors that inform the central nervous system about the environment both within and outside the body. J Cutan Pathol 21: 457-460. The Pacinian corpuscle is a mechanoreceptor, mainly associated with the detection of vibration. Four such tumours collected over the course of 20 years are described and the … A Pacinian corpuscle is an onion-shaped structure of nonneural (connective) tissue built up around the nerve ending that reduces the mechanical sensitivity of the nerve terminal itself. The histology, presenting features and associated conditions are discussed in detail. A linear incision was made on the medial aspect under local anaesthesia using 2% lignocaine and tourniquet control (Figure 3). They are distributed in fingers (60%), near the metacarpophalangeal joints (25% to 48%) and in the thenar and hypothenar regions (8% to 18%) [1]. Cross sectional histology of the proximal segment of the thumb from a fetus of CRL 290 mm. The excised mass was sent for histopathological examination. (2000) A Pacinian hyperplasia of the foot. The Pacinian corpuscle is a pressure receptor that responds to high-frequency vibratory stimuli. They should be looked for when dissecting the palm of the hand and fingers. HE staining (panel A) and immunohisto- chemical staining with antibodies to SMA (panel B), S100 protein (panel C) and nestin (panel D). We present an interesting case of a woman with Pacinian corpuscle neuroma of the thumb. We frequently noted hyperintense nodules in the palms of patients on water-sensitive MRI sequences, but were unable to explain their etiology. Capsule of Pacinian corpuscle (histological slide) Displacement of the skin compresses the corpuscle and triggers an action potential in the nerve ending. Presentation may vary from digital pain to macrodactly [2-8]. Pacinian corpuscles.  Link: Fletcher CD, Theaker JM (1989) Digital pacinian neuroma: A distinctive hyperplastic lesion. Report of a case associated with foreign body reaction. Based on previous descriptions, subcutaneous nodules representing presumed Pacinian corpuscles were localized with respect to the skin markers, and their … This lesion can be called variably as Pacinian corpuscle hyperplasia or Pacinian corpuscle neuroma [2-7]. The subcutaneous distribution and number of Pacinian corpuscles were studied in ten fresh cadaver hands. Scale bar, 100 µm. Palmar Skin, Pacinian corpuscles 40X The arrow in this image points to a Pacinian corpuscle, a type of sensory receptor located in the deep part of the dermis or in the hypodermis. The definitive diagnosis and treatment of this disease are possible if surgical resection is performed after careful consideration of differential diagnoses. These corpuscles are found deep in the skin within the layers of reticular dermis and hypodermis. It consists of a single nerve fibre, the terminal region of which is enclosed in a multilaminated connective tissue capsule. These receptors respond to pressure and vibration and can be up to 1 mm in diameter. A prior history of trauma may be elicited in a majority of the patients and it may be associated with foreign body reaction [8]. Immediately in the subcutaneous plane, shiny clusters of mass were seen clumped together and they seemed to be under tension. When Pacinian corpuscles, which are also called lamellar corpuscles, are deformed by pressure, they cause action potentials or nerve impuls… Pacinian corpuscles are the largest sensory structures in the skin, so they are easy to find. When pressure is applied to them they respond by sending signals to the central nervous system. It is a sensory end organ consisting of concentric layers or lamellae of connective tissue and ground substance surrounding a nerve ending. Sweat glands, their ducts, blood vessels and sensory receptors (Pacinian corpuscles), are located deep in the dermis or in the adjacent hypodermis. All of the visible masses were excised. A cadaver study. Meissner's and Pacinian corpuscles are cutaneous mechanoreceptors responsible for different modalities of touch. Link:  Patterson TJ (1956) Pacinian corpuscle neuroma of the thumb pulp. These receptors are lamellar vibration receptors that produce rapidly adapting responses. The dermis of skin consists of two layers, a thin papillary layer immediately beneath the epidermis and a thick reticular layer. Pacinian corpuscle neuromas are rare, with only about few cases reported in the literature. Histopathological features were consistent with a Pacinian corpuscle neuroma (Figures 4,5). Pacinian corpuscles contain a myelinated nerve ending in the central core of the structure. They were found to cluster close to nerves and vessels at the metacarpophalangeal joints and the proximal phalanx. This is a pacinian corpuscule. , Pacinian corpuscles) respond only to mechanical deformation. The outer layers are composed of flattened cells, collagen fibers and a lymph-like fluid.

Pacinian corpuscles are encapsulated sensory receptors located in the deep layer of the dermis and in the hypodermis. Pacinian corpuscles are colored red, and nerve elements are colored yellow. They include Pacinian neuroma of vulva, Pacinian hyperplasia of foot, sacrococcygeal pacinioma and intraperitoneal pacinian neuroma [9-13]. Scale bar, 100 µm. In the ligament, this receptor is quite small with a diameter of 20 to 50 μm. Pacinian Corpuscles. The patient had complete pain relief following excision of the tumor. Finger movements were near normal. Stark B, Carlstedt T, Hallin RG, Risling M (1998) Distribution of human Pacinian corpuscles in the hand. These corpuscles are sensitive to deep or heavy pressure and to vibrations up to 400 cycles a second. The epidermal layer that corresponds to the structure indicated as #2 can be correctly identified as the: … Scale bar, 500 µm. On examination, there was normal skin and nail complex. There are approximately 300 Pacinian corpuscles in the hand. The hypodermis lies beneath the skin but is not part of it. 3-T MRI of a cadaveric hand specimen was performed with fiduciary markers on the skin. © 2003 - 2021 - Mathias Nordvi - All rights reserved. A provisional diagnosis of a Glomus tumour was made. More particularly, they are primarily located just beneath the epidermis within the dermal papillae. Patient was discharged on the 2nd postoperative day and skin sutures were removed on the 14th postoperative day.  Link: Rinaldi P, Andreini A, Ercolani C, Bernardi L, Bernardi S (2000) Digital pacinian hyperplasia. Histopathology 19: 89-90. 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. Section D: Pacinian Corpuscle #2. There was no history of previous pain. Pacinian corpuscles are mechanoreceptors found in man and other animals. Flexor tendons were intact with no compressibility, pulsations or thrill and no distal neurovascular deficit. Pacinian corpuscles have a single axonal fiber at the center surrounded by 15-20 lamella arranged in a concentric pattern. J Hand Surg 23: 370-372. They are located in the subcutaneous tissue, deeper in interosseous membranes, and also mesenteries of the gut. A neuroma may sometimes arise from this Pacinian corpuscle. It is a sensory end organ consisting of concentric layers or lamellae of connective tissue and ground substance surrounding a nerve ending. Even though the Pacinian corpuscle is typically located in the skin, histomorphologically and confirmed by using immunohistochemical methods, we have identified it within the interstitium of the thymus of a newborn with congenital heart defect. To provide microdissection and histological confirmation of normal Pacinian corpuscles prospectively identified using MRI in a cadaver model. 19. Br J Plast Surg 9: 230-231. 2-1 C). Foot Ankle Int 22: 342-344. Pacinian corpuscle neuroma is an uncommon lesion with a limited number of cases reported. Pacinian corpuscle definition, a microscopic, onionlike body consisting of layers of connective tissue wrapped around a nerve ending, located in the deep layers of skin, tendons, etc., and functioning as a sensory receptor of pressure and vibration. The development of these sensory formations in humans is poorly known, especially regarding the acquisition of the typical immunohistochemical profile related to their full functional mat … (g) A Pacinian corpuscle on the surface of the periosteum in the insertional angle deep to a fibrous band extending from the ITB to the femur.
