& WILSON-JONES (1977)Histopathology I, 247-255 E. Pacinian neurofibroma At rare intervals in the literature, reports have appeared of a skin tumour containing structures resembling Pacinian corpuscles. The excised mass was sent for histopathological examination. Nevertheless, their existence is largely unknown to most radiologists. The authors discuss an interesting case of a Pacinian corpuscle neuroma in the finger of a young woman who presented with severe digital pain. © 2020 Singh SK, et al. DISTRIBUTION OF INITIAL PACINIAN CORPUSCLES155 Fig. Pacinian corpuscles are the capsulated endings of sensory neurons. Paccinian corpuscles These look like 'onion' bulbs, and are commonly found in the dermis and subcutaneous tissue. Neural tumours composed exclusively of Pacinian corpuscles or showing focal Pacinian differentiation are extremely rare and have only occasionally been reported in the literature.  Link: Bale PM (1980) Sacrococcygeal paciniomas. J Hand Surg 7: 113-117. They are distributed on various areas of the skin, but concentrated in areas especially sensitive to light touch, such as the fingers, lips and nipples. 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. On examination, there was normal skin and nail complex. J Hand Surg 23: 370-372. Stark B, Carlstedt T, Hallin RG, Risling M (1998) Distribution of human Pacinian corpuscles in the hand. The pain was diffuse and severe over whole of the thumb and was even tender to light touch. The definitive diagnosis and treatment of this disease are possible if surgical resection is performed after careful consideration of differential diagnoses. The patient had complete pain relief following excision of the tumor. When Pacinian corpuscles, which are also called lamellar corpuscles, are deformed by pressure, they cause action potentials or nerve impuls… A 32-year-old female patient presented to the Department of Orthopaedics with pain of right thumb since last 8 months. They are large oval structures that are 0.5 to 1 mm in diameter.

There are approximately 300 Pacinian corpuscles in the hand. Pacinian corpuscles. (2000) A Pacinian hyperplasia of the foot. Pacinian corpuscles, the main touch receptors to pressure and vibration, are ubiquitous in the deep dermis and hypodermis of the fingers and palms. The symptoms of this disease are usually alleviated after complete resection. In the ligament, this receptor is quite small with a diameter of 20 to 50 μm. These corpuscles are found deep in the skin within the layers of reticular dermis and hypodermis. The afferent nerve ending at the centre is enveloped by multiple concentric layers of flattened cells and an external capsule of connective tissue. Female Reproductive Histology. The clinical signs were very prominent.  Link: Rinaldi P, Andreini A, Ercolani C, Bernardi L, Bernardi S (2000) Digital pacinian hyperplasia. It consists of a single nerve fibre, the terminal region of which is enclosed in a multilaminated connective tissue capsule. Presentation may vary from digital pain to macrodactly [2-8]. Routine blood investigations, ECG, chest X-ray, X-ray of the right hand and an MRI were done. They are distributed in fingers (60%), near the metacarpophalangeal joints (25% to 48%) and in the thenar and hypothenar regions (8% to 18%) [1]. The hypodermis lies beneath the skin but is not part of it. Several autoimmune diseases such as gout, exostosis, and arthritis can also present as this condition [17]. The percentage of the total was 44 to 60% in the fingers, 23 to 48% in the metacarpophalangeal area and 8 to 18% in the thenar and … 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.

They are the largest mechanoreceptors in the body and are important to recognize as they may be mistaken for pathology. These end-organs are the only sensory receptors that are large enough to be identified and dissected in the anatomy laboratory. One month hence, the patient had complete pain relief. The total mean number in the hand was 300 (192-424). The nerve ending is surrounded by many layers … Both basic structure and immunohistochemical characteristics were reached at 36 weeks GA. Pacinian corpuscles are rapidly adapting receptors and respond to acceleration, or the onset/cessation of displacement of the skin. This lesion can be called variably as Pacinian corpuscle hyperplasia or Pacinian corpuscle neuroma [2-7]. Scale bar, 100 µm. Pacinian corpuscle neuromas may be associated with other lesions such as glomus tumour, Dupuytren’s contracture, multiple Pacinian neuroma and arteriovenous anastomoses [14-16]. To provide microdissection and histological confirmation of normal Pacinian corpuscles prospectively identified using MRI in a cadaver model. Section D: Pacinian Corpuscle #2. Histology crossing along planes B and C are shown in panels B and C, respectively. The histology, presenting features and associated conditions are discussed in detail. 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. The most common site of this lesion is the hand, where it presents as painful swelling. A linear incision was made on the medial aspect under local anaesthesia using 2% lignocaine and tourniquet control (Figure 3).  Link: Medina Perez M, Rafel Ribas E, Valero Puerta JA, Perez Martin D (2000) Pacinian neurofibroma of the vulva.

J Hand Surg 16: 865-869. In between the lobules there is a large onion shaped structure. When making a differential diagnosis of unexplained severe pain in the hand, Pacinian corpuscle should be considered in addition to benign tumors of non-neural origin, such as hemangiomas, fibromas, ganglion cysts, mucoid cysts and angiolipomas, and neural origin, including schwannomas and glomus tumors, as the cause of a tender digital papule. Pacinian corpuscles are sensitive to mechanical and vibratory pressure. Meissner's and Pacinian corpuscles are cutaneous mechanoreceptors responsible for different modalities of touch. More particularly, they are primarily located just beneath the epidermis within the dermal papillae. 2-1 A and B) surrounded by layers of perineurial lamellae, which create a distinguishing capsule (see Fig. Link: Kim SW, Jung SN (2011) Glomus tumor within digital nerve: a case report.

Arch Esp Urol 53: 634-636. Histopathology 15: 249-256. Pacinian corpuscles are the largest sensory structures in the skin, so they are easy to find. 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. Pacinian corpuscles are encapsulated sensory receptors located in the deep layer of the dermis and in the hypodermis. This is a pacinian corpuscule. We frequently noted hyperintense nodules in the palms of patients on water-sensitive MRI sequences, but were unable to explain their etiology.
