Angiokeratoma circumscriptum vascular lesions are defined by ectasia of the papillary dermal vessels, and the etiology is unknown. We report a rare case of angiokeratoma circumscriptum following the excision of a lipoma, from the same area, on the right foot 3 years prior. Therefore, this case indicates that the injury could be involved in the development of angiokeratoma circumscriptum.

| Introduction|| |
Since the first description of angiokeratomas in 1890, angiokeratomas can be classified into five types: (1) angiokeratoma of Mibelli; (2) angiokeratoma of Fordyce; (3) angiokeratoma corporis diffusum; (4) angiokeratoma circumscriptum; and (5) solitary or multiple angiokeratomas., Angiokeratoma circumscriptum was first described by Fabry in 1915, which is the least frequent among the five types of angiokeratomas, and the etiology is unknown, and its lesions are usually present at birth and may be associated with cavernous hemangioma, nevus flammeus, or hemangiectic hypertrophy.
| Case Report|| |
A 5-year-old Chinese child presented with a 1-year history of plaques and red to black-colored papules on the right foot. The child accepted the excision of a lipoma on the same area 3 years ago. Examination revealed plaques and black-colored papules, measuring 0.2–10 mm, forming a coalescent plaque predominantly on the medial malleolus of the right foot [Figure 1]. Initially, the lesion was small red plaque confined to the excision scar. Subsequently, the plaque areas became hyperkeratotic with age. The lesion was asymptomatic except for symptom of pruritus. There was no relevant family history. A dermoscopic pattern presented by dark lacunae, whitish veil, and peripheral erythema with hemorrhagic crust [Figure 2]. The biopsy specimen from a representative papule showed dilated thin-walled capillary capillaries with hyperkeratosis and acanthosis [Figure 3]. According to the clinical and histopathological features, angiokeratoma circumscriptum was diagnosed. No recurrence has been observed during a 6 months' follow-up period after treated with an intense pulse light source.

Dilated vascular spaces in the papillary dermis with thrombosis presented as dark lacunae. Hyperkeratosis and acanthosis appeared as a whitish veil.

| Discussion|| |
Angiokeratoma circumscriptum is typically situated on the lower legs or feet in a unilateral or otherwise asymmetrical distribution involving the thighs, buttocks, trunk or occasionally other areas. Clinically, angiokeratoma circumscriptum is characterized by aggregates of hyperkeratotic erythematous papules (deep red to blue–black in color) and nodules, which may coalesce to form verrucous plaques. The lesions become increasingly studded with warty keratotic papules or nodules. There is no tendency to spontaneous regression.
Angiokeratoma circumscriptum is often misdiagnosed as verrucous hemangioma, Cobb syndrome, angioma serpiginosum, lymphangioma circumscriptum, verrucae, malignant melanoma. However, in the dermoscopic view, these above lesions hardly show whitish veils. Dermatoscopy is useful for the diagnosis of angiokeratoma.
Angiokeratoma circumscriptum's histopathology consist of dilated, thin-walled, congested papillary dermal vessels with secondary epidermal reaction changes, such as acanthosis and/or hyperkeratosis, without involvement of the deep dermis, which are thought to be a vascular lesion arising from local damage of papillary capillaries.
The angiokeratomas are rare verrucous vascular lesions that appear as dark red papules and plaques arranged either discretely or in clusters. As Imperial and Helwig wrote, these lesions are not true angiomas but are merely telangiectasias of preexisting vessels. The exact etiology is unknown, although congenital cause, pregnancy, chilblains, trauma, and tissue asphyxia are given as causal factors. There have been few reports of angiokeratoma circumscriptum following the excision of lipoma. We report a rare case of angiokeratoma circumscriptum following the excision of a lipoma, from the same area, on the right foot 3 years prior. Therefore, this case indicates that injury could be involved in the development of angiokeratoma circumscriptum.
