Basaloid follicular hamartoma is associated with a variety of disorders and is caused by mutation in the PTCH gene. The diagnosis is made based of histopathological examination.
Signs and symptoms edit
Basaloid follicular hamartoma manifests as multiple 1- to 2mm tan-to-brown-colored papules located on the pubic area, trunk, axilla, scalp, and face.[2]
Causes edit
Basaloid follicular hamartoma can be hereditary or acquired.[3]
Associated conditions include cystic fibrosis, systemic lupus erythematosus, myasthenia gravis, hypohidrosis, hypotrichosis, palmar pitting, and alopecia.[2]
Basaloid follicular hamartoma is caused by a mutation in the chromosome 9q23 patch (PTCH) gene, which is also the gene responsible for nevoid basal cell carcinoma syndrome.[4]
Diagnosis edit
The diagnosis of basaloid follicular hamartoma lesions requires a histopathological investigation.[2] Histopathological features include basaloid epithelial cells in the papillary dermis form multifocal islands and branching cords, some of which are attached to the epidermis and dilated hair follicles.[5]
Treatment edit
Various interventions, including photodynamic therapy, carbon dioxide laser, and surgery, have been suggested.[5]
