Cutaneous schwannoma presenting as a lower back mass

Abstract

HighlightsSchwannomas are benign neoplasms composed of Schwann cells, that can arise anywhere in the body.Schwannomas arise mainly in the dermal and subcutaneous tissue layers.In this case report, we present a cutaneous schwannoma presenting as an enlarging left lower back solitary mass that was surgically excised.

Paraspinal plexiform schwannoma of unknown nerve origin: A case report

“…Schwannomas may occur at any location where Schwann cells are present [ 9 ]. The rarity and wide variety of clinical manifestations may lead to delayed diagnosis and a management plan without specific protocols [ 2 ].…”

“…The areas of highest incidence include the head, neck, mediastinum, retroperitoneum, and flexor surfaces of the extremities [ [6] , [7] , [8] ]. The vestibulocochlear nerve (CN VIII) eight is the most common cranial nerve of origin [ 9 ].…”

Cutaneous Ancient Schwannoma of the Ear

“…4 Schwannomas occur most commonly during the fourth and fifth decade of life, without significant evidence of sex predilection. [3][4][5] In general, cutaneous schwannomas are asymptomatic. 5 However, as they grow larger, pain, paresthesias, and tenderness can occur, associated with the compression of the nerve of origin or adjacent structures.…”

“…[3][4][5] In general, cutaneous schwannomas are asymptomatic. 5 However, as they grow larger, pain, paresthesias, and tenderness can occur, associated with the compression of the nerve of origin or adjacent structures. 5 The clinical diagnosis is challenging due to the non-specific presentation, becoming necessary to exclude other well-circumscribed skin masses such as lipoma, angiolipomas, leiomyomas, cysts, neurofibromas, and neuromas.…”

“…3). [1][2][3][4][5][6] In Antoni A areas, uniform spindle cells are clustered in stacks and arranged back to back, creating palisades of stacked nuclei between which the cell processes are fused into eosinophilic masses, called Verocay bodies (Fig. 3 A, B).…”
