What Is Your Diagnosis? Eruptive Syringoma

A 45-year-old woman presented with multiple flesh-colored to slightly hyperpigmented papules on the face, neck, axillae, chest (left), cubital fossae, medial forearms (right), anterior abdomen, and groin. The papules were approximately 3 to 4 mm in diameter and were not painful or pruritic. The papules first appeared at 13 years of age and became enlarged during her premenstrual cycle. Her medical history was otherwise unremarkable. A 4-mm skin biopsy was taken from the right forearm.
