Angiokeratoma is described by various authors as a rare variant of the hemangioma in the dog, characterized by a vascular component, like all types of vascular neoplasms, but also by an epithelial component. A case of angiokeratoma is described in a male 8-year-old dog. The tumor was located in heavily pigmented skin on the anterior surface of the front limb and not in the more usual previously described locations, eyelid and conjunctiva. Microscopic examination revealed a well-circumscribed mass with irregular hyperplasia of the epidermis and dilated vascular spaces filled with blood in the superficial dermis.

Angiokeratomas are benign vascular lesions characterized by ectatic blood vessels in the papillary dermis with overlying acanthosis and hyperkeratosis, often occurring as idiopathic scrotal tumor and rarely as penile lesions. Twelve men, including our case of a 58-year-old white man, have been reported with angiokeratomas of the glans penis. The lesions typically present as asymptomatic dome-shaped papules ranging in size from 0.5 to 5 mm and present as red, purple, blue, or black lesions along the penile coronal rim. Histopathologic examination of the lesions reveals dilated, thin-walled vascular structures in the upper portion of the dermis with overlying acanthosis and/or hyperkeratosis. Such angiokeratomas may have a multifactorial etiology with elevations in local venous pressure, degeneration of elastic tissue, and/or capillary injury. Biopsy would exclude a melanocytic lesion, particularly melanoma. Laser surgery is an option for patients presenting with multiple lesions or lesions that coalesce to form a plaque.

Acral angiokeratoma-like pseudolymphoma is a rare type of pseudolymphoma presenting as dark-red papules on the hand or foot. We describe a 59-year-old woman who presented with an unusual unilateral, clustered aggregate of scaly violaceous papules on the toe with an indolent course. Skin biopsy showed a prominent vascular proliferation associated with a dermal infiltrate of monoclonally rearranged T-follicular helper phenotype T-cells, in keeping with CD4+ small/medium T-cell lymphoproliferative disorder (SMPTC-LPD). Based on the unique clinical morphology, distribution of the lesions and dermoscopic appearance, a clinicopathologic diagnosis of acral angiokeratoma-like pseudolymphoma was favored. This case demonstrates the importance of clinicopathological correlation in such diagnostically challenging patients who present with overlapping features on the spectrum of pseudolymphoma and cutaneous T-cell lymphoma.

We have presented a 12-year-old boy with angiokeratoma circumscriptum on his left knee. The lesion first appeared at the age of eight as a dark brown nodus with the verrucous surface. It bled easily even after mild trauma this being a principal reason for the hospital admission and surgical excision in toto. Pathohistological examination confirmed the clinical diagnosis. Differential diagnosis, clinical and pathohistological findings, as well as therapy of the disease have been discussed in some detail.
