Trichostasis Spinulosa: A Case Report with an Unusual Presentation

Abstract

Trichostasis spinulosa (TS) is a follicular disorder characterized by the retention of multiple vellus hairs in a hyperkeratotic dilated hair follicle. TS is considered as a common disorder; however, it is often underdiagnosed due to its asymptomatic nature. Although the condition frequently affects the face or extremities, the widespread distribution of TS over the entire body has been once reported in a patient with chronic renal failure. To emphasize the infrequent presentation of TS, we herein report a 57-year-old male with an unusual location of TS.

Two new dermoscopic features of trichostasis spinulosa and its reflectance confocal microscopic appearance

“…Two clinical variants of TS have been proposed, namely non-pruritic and pruritic type [ 3 ]. We present a patient classified as pruritic type which usually affects young adult characterized by multiple itchy follicular papules mainly on the trunk and upper limbs.…”

A Case Report of Sebaceous Filaments

“…Trichostasis spinulosa is a common disorder of hair follicles that presents as darker papules on the face and extremities [ 7 ]. Diagnosis can be confirmed by dermoscopy or histology which shows hyperkeratinous sheaths surrounding vellus hairs in dilated follicles [ 7 ]. Treatments are not curative but can manage symptoms [ 7 ].…”

“…Diagnosis can be confirmed by dermoscopy or histology which shows hyperkeratinous sheaths surrounding vellus hairs in dilated follicles [ 7 ]. Treatments are not curative but can manage symptoms [ 7 ]. These include topical keratolytics, emollients, tretinoin, and laser treatments [ 7 ].…”
