Angiokeratoma circumscriptum in a young male

Localized Angiokeratomas in healthy adolescence responded to topical Timolol

Angiokeratoma (AK) is an uncommon vascular cutaneous illness that is characterized by benign vascular ectasias of the papillary dermis combined with papillomatosis, acanthosis, and hyperkeratosis of the epidermis. It often presents as mainly asymptomatic. Here, we present a case of a 14-year-old Saudi male who presented to the dermatology clinic with red-to-black nodules of varying sizes on the palmar and dorsal surfaces of his left hand. Upon examination, the nodules were painless with no other constitutional symptoms. Laboratory investigations were unremarkable. A 4-mm skin punch biopsy showed dilated vascular channels at the papillary dermis and corneal layer with acanthotic epidermis with granulation tissue; these findings were suggestive of AKs of Mibelli. Timolol drops were prescribed twice daily for 1 month, and the patient was seen after a month with a 90% resolution of lesions. This case study describes an intriguing instance of eruptive AK of Mibelli that was treated with Timolol 0.5% drops and was localized unilaterally over the left hand in a youngster who had previously been in good health. To the best of our knowledge, no previously reported AK of Mibelli cases that responded to Timolol 0.5% drops.

Solitary Angiokeratoma in a Young Man: A Rare Case Report

Angiokeratoma is a rare vascular cutaneous disorder that usually presents as mostly asymptomatic aside from multiple dark red to blue or black papules over the skin in several clinically distinct conditions. Very rarely, it occurs in solitary localized forms that clinically mimic vascular disorders or sometimes melanoma. Solitary cutaneous angiokeratoma may result from damage to a venule's wall in the papillary dermis. This case study describes a 28-year-old male with a single angiokeratoma on the lateral aspect of his upper thigh and a clinical suspicion of a cutaneous melanocytic tumor. This case is intended to raise awareness about such rare skin lesions and the importance of histopathological examination.

Solitary Angiokeratoma: Report of Two Uncommon Cases

Angiokeratomas are rare benign vascular skin lesions arising in isolation or in groups of multiple lesions, as solitary cutaneous forms or generalized systemic forms. They are ectasias of dermal capillaries with an acanthotic and hyperkeratotic epidermis. They can occur in both healthy individuals and in those with underlying systemic disease due to inherited enzyme deficiency or other acquired predisposing factors. The identification and reporting of these lesions is important as patients with these lesions should be evaluated to rule out underlying pathogenic conditions. We report two rare cases of isolated solitary cutaneous angiokeratoma occurring in two patients.
