Basaloid follicular hamartoma is characterized by tumor growth in the hair follicle primarily of the face and scalp. Basaloid follicular hamartomas are divided into two categories: congenital (present at birth) or acquired (appear later in life). Symptoms are small lesions which can appear on the face, scalp, neck, upper body, arms, palms of hands and soles of feet. They range in color from skin-colored to brown. While some of the symptoms are similar to that of skin cancer, they are quite different as basaloid follicular hamartoma is almost always benign (non-cancerous). Although the lesions are typically stable and slow growing for many years, they need to be monitored due to the rare potential for them to become cancerous. Diagnosis is made by a skin biopsy. Since basaloid follicular hamartomas are usually harmless, treatment is typically not needed. In some cases, people opt to remove them if they are in sensitive region.
Basaloid follicular hamartoma may be inherited in an autosomal dominant manner. We inherit our genes in pairs, one from each parent typically. Our genes are what control the growth, development and function of our bodies. If a mistake or error occurs in a gene, it can cause problems. Autosomal dominant means that if one parent has the condition (therefore the mutation) there is a 50% chance that they will pass it on to each of their children. However sometimes the mutation or change is sporadic or new (de novo), meaning it occurred when the egg or sperm was being made in one parent. Neither parent therefore would have the condition, but the individual affected with the condition now has a 50% chance of passing it to their own children. Mutations in the PTCH gene have been linked to this condition. If you have skin changes such as these or a family history of basaloid follicular hamartoma, you should speak with your doctor to determine if any treatment is required and the most current treatment options.
