Living with Generalized basaloid follicular hamartoma syndrome

A rare genetic skin condition with many tiny bumps on the face, neck, and upper body, and sparse hair.

Understanding Generalized basaloid follicular hamartoma syndrome

Generalized basaloid follicular hamartoma syndrome is a rare genetic skin disease with many tiny skin bumps.

People have many small, skin-colored or darker bumps (1 to 2 mm) that look like milia or blackheads. They also have thin hair and small pits on the palms and soles. The bumps are usually first seen on the cheeks or neck and slowly grow in size and number to reach the scalp, face, ears, shoulders, chest, armpits, and upper arms. Mild reduced sweating has been reported.

Signs & symptoms

GARD lists these among the main features:

  • Many tiny skin-colored or darker bumps
  • Bumps that look like milia or blackheads
  • Thin or sparse hair (hypotrichosis)
  • Small pits on the palms and soles
  • Mildly reduced sweating (hypohidrosis)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
