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.

We present a patient with Pacinian corpuscle hypertrophy and hyperplasia in the hand and discuss the diagnosis and treatment of this rare condition. A 46-year-old woman presented with radiating pain of the left middle finger. A strong Tinel-like sign was elicited between the index and middle fingers. The patient frequently used mobile phone, with the corner of the phone consistently applying pressure on the palm. The surgery was carried out under the microscope and two enlarged cystic lesions under the epineurium were found in the proper digital nerve. Histologic examination revealed hypertrophied Pacinian corpuscle with normal structure. Postoperatively, her symptoms gradually improved. Preoperative diagnosis of this disease is very difficult. Hand surgeons should keep this disease in mind preoperatively. In our case, we would not have been able to identify multiple hypertrophic Pacinian corpuscles without the microscope. An operating microscope is recommended in a surgery of this nature. Level V (Therapeutic).

The fortuitous finding of a complex Pacinian corpuscle within the lamina propria of the human urinary bladder is described. It consisted of a complex of encapsulated nerve endings within the areolar connective tissue of the lamina propria immediately adjacent to the inner aspect of the detrusor muscle. It showed no structural evidence of directional sensitivity and was associated on its outer aspect with small unmyelinated axons containing small clear and dense-cored vesicles. This appears to be the first report of an encapsulated nerve ending within the lining of the adult human urinary bladder.

An improved model of the Pacinian corpuscle includes corrections for lamellar curvature. Results suggest that outer-zone lamellae produce a focusing effect whereby stimuli are channeled radially inwards. The requirements for this effect (large outer-surface area and thin, closely spaced lamellae) provide a rationale for the complexity of the outer-zone structure.

Occlusion of the mesenteric vessels in the cat and injection of catecholamines produced significant changes in skin and muscle blood flows. These were abolished by cutting the mesenteric nerves. The occurrence of systemic pressure and peripheral resistance changes in cross-perfused mesenteric preparations indicates that hemodynamic factors alone, such as might result from occlusion of a large vascular region, were not initiating the reflex. This also excludes extramesenteric receptors within the heart and large vessels from the reflex. Since both intravascular pressure and catecholamines have been shown to modify Pacinian receptor discharge in vivo, the evidence suggests that the mesenteric Pacinian corpuscle is the baroreceptor probably initiating the vasomotor reflexes in skin and muscle. The net effect of mesenteric receptor activity appears to be an inhibition of vasomotor neurons supplying skin and muscle.
