A Case of Basaloid Follicular Hamartoma

Abstract

Fig. 1. The skin lesion is solitary, skin colored, 0.6×0.6 cm, and smooth, with a central depressed papule on the left forehead.

“Kissing” basaloid follicular hamartomas of the eyelid

“…BFHs are rare, benign malformations of the hair follicles with variable clinical manifestations including flesh‐colored papules, plaques, and nodules most commonly located on the face. They may also be distributed in the areas of the terminal hair including the scalp, axillae, and pubic regions 11 . In our case, the patient presented with umbilicated lesions, a feature not classically seen in this condition.…”

“…In our case, the patient presented with umbilicated lesions, a feature not classically seen in this condition. BFHs are classified as hereditary or acquired with the hereditary form including generalized and unilateral nevoid types 11 . The generalized familial form of BFHs may be associated with autoimmune diseases such as systemic lupus erythematosus, alopecia, Graves disease, and myasthenia gravis 11 .…”

“…BFHs are classified as hereditary or acquired with the hereditary form including generalized and unilateral nevoid types 11 . The generalized familial form of BFHs may be associated with autoimmune diseases such as systemic lupus erythematosus, alopecia, Graves disease, and myasthenia gravis 11 . To the best of our knowledge, there are only four prior reported cases of BFHs on the eyelid, including one case in a pediatric patient 3–6 …”

Congenital hypotrichosis, eruptive milia, and palmoplantar pits: A case report with review of literature

“…GBFHS and BCC are not related but malignant transformation to BCC has been reported. [ 8 9 ] Unlike NBCCS, there are no odontogenic cysts, keratocysts, skeletal anomalies, and predisposition to internal malignancy. Screening the PTCH1 gene for mutation can differentiate NBCCS from GBFHS, as mutation is present in the former.…”

Segmentally Arranged Hyperpigmented Basaloid Follicular Hamartoma

“…Twenty-nine cases of BFH have been reported thus far. In Korea, there have been several cases of skin-colored, localized or multiple, scattered BFH 4 , 5 . Our case is unique owing to its clinical features: hyperpigmented, segmentally, and linearly arranged lesions with unilateral distribution.…”
