“…Other dermoscopic features that have been described in TS include circle hair and rolled hair. [ 3 5 ] However, these are not specific to TS. In addition, novel dermoscopic features were noted in our case, which was a reddish homogenous area adjoining the follicular keratosis or hair tuft.…”

Trichostasis spinulosa is a disorder of hair follicles characterized by the retention of vellus telogen club hair, leading to the formation of comedo-like lesions. It usually presents over the face and is frequently asymptomatic. We report a 53-year-old female who presented with multiple itchy, discrete, bluish-black, 2–3 mm comedo-like follicular papules and pustules on her breast and lower abdomen for the past 2 years. In-vivo dermoscopy showed keratotic plugs with a tuft of hair. Extraction dermoscopy yielded a cystic structure filled with keratin and multiple vellus telogen club hairs. Histology showed a cyst lined by squamous epithelium containing abundant laminated keratinous debris and a vellus hair shaft. Truncal or breast involvement, as seen in the present case, is relatively rare, and can be pruritic, causing significant morbidity due to itching and secondary bacterial infections. Dermoscopy, especially ex-vivo extraction dermoscopy, can show diagnostic features and obviate the need for abiopsy.

Introduction: Rosacea is a chronic inflammatory skin condition with several clinical subtypes, including phymatous rosacea, which is distinguished by thickened skin, enlarged pores, and irregular surface nodularities, primarily affecting the nose. This manuscript aims to explore the underrecognized connection between early to moderate phymatous rosacea and trichostasis spinulosa (TS), a follicular disorder characterized by the retention of multiple telogen hairs. Methods: A total of consecutive 13 patients with initial phymatous changes and black dilated openings were enrolled. Detailed dermatological assessments, including dermoscopy, were conducted to identify and confirm trichostasis spinulosa. Dermoscopy of the black openings confirmed the presence of hair tufts emerging from dilated follicular openings and plugs. Patients underwent minor procedures using a comedo extractor to remove the hair bundles. Results: All extracted follicular units showed typical characteristics of trichostasis spinulosa, including bundles of telogen hairs surrounded by a sebokeratinous plug. Conclusion: We postulate that the fibrotic processes characteristic of phymatous rosacea may promote the development of TS. Recognizing TS as an early indicator of phymatous rosacea could help prevent disease progression.
