Clinical and dermoscopic features of lichen planus pigmentosus in 37 patients with frontal fibrosing alopecia

Hyperpigmented Upper Eyelid: A Clue to the Diagnosis of Facial Lichen Planus Pigmentosus in a Patient with Frontal Fibrosing Alopecia

“…The finding of a classic LPPig on the upper eyelid, sharing typical LPPig dermoscopy features [2, 5] and characteristic histopathological findings [9-11], may call attention to the fact that the eyelid involvement may not be anecdotal. Instead, it may be an important clue to the diagnosis of LPPig that helps differentiating it from other common photodermatoses such as melasma because the upper eyelid is a well-known sun-protected area.…”

A face biopsy is not always possible to perform, as pointed out in the work of Pirmez et al [5], and in late stages, the characteristic lichenoid dermatitis may already have disappeared.…”

“…2). Dermoscopy interpretation and description were based on studies conducted by Sharma et al [2] and Pirmez et al[5]. …”

Successful Treatment of Facial Papules in Frontal Fibrosing Alopecia with Oral Isotretinoin

Currently, several authors consider FFA as a generalized skin condition, and many features other than hair loss have been associated with the disease, including facial papules [2].…”

Red Dots in a Net-Like Pattern on the Upper Chest: A Novel Clinical Observation in Frontal Fibrosing Alopecia and Fibrosing Alopecia in Pattern Distribution

“…As previously described [9,10], lichen planus pigmentosus in FFA patients may display affected areas other than the face, such as the neck and cleavage area. The reticular pattern presented on dermoscopy is reminiscent of the reticulated pattern described for lichen planus pigmentosus.…”
