Hemangiomas are benign vascular proliferations characterized by hyperplasia of different types of blood vessels. Infantile hemangiomas and cherry angiomas are the most common vascular proliferations in children and adults, respectively.1
Benign tumors

Any bleeding can be stopped with gentle pressure and the eroded area gradually heals with routine care. One other rare complication only occurs with the largest of capillary angiomas. Blood platelets become sequestered in the abnormal vascular channels of the angioma, creating a consumption coagulopathy and uncontrolled bleeding (Kasabach–Merritt syndrome).

Antithrombotic therapy is important, such as daily aspirin. Glaucoma should be treated (with beta-blockers, carbonic anhydrase inhibitors, or trabeculectomy). Educational assessment is important to identify learning difficulties and provides appropriate support. The most severely affected patients are those with bilateral disease who are not good surgical candidates. Laser treatment of the face is effective in eliminating the facial angioma and usually begins in the second to third year of life.
A rare case of intramuscular angioma involving the medial rectus muscle

Intramuscular angioma is a rare tumor type accounting for less than 1% of the total number of hemangiomas.2,6 Of this small number of tumors, 15% will originate in the head and neck; the masseter muscle being the most common site of head and neck IMH followed by the trapezius, sternocleidomastoid, temporalis, masseter and mylohyoid muscles.2,3,11–18 Orbital extraocular muscle angiomas are exceedingly rare and to date only a few cases have been reported.5–8 IAs in general, are thought to be congenital in origin and result from an arrest in the development of the mesenchymal primordia in the earliest stage of vascular system formation.2,19 They tend to grow slowly as nonencapsulated masses and histopathologically are composed of a mix of lymphatics, thick walled veins, a mixture of cavernous-like vascular spaces and capillaries or an arteriovenous component.2 Variable amounts of mature adipose tissue are almost always present. In one series, approximately 50% are of the capillary type, followed by the cavernous type seen in 29% of patients and the mixed type, which represents 21% of cases.3 IAs may remain undetected for a long time until growth eventually causes symptoms.2 Most are present before the fourth decade and spontaneous regression has not been reported to date.2,4

An acquired capillary haemangioma can be easily confused with pyogenic granuloma or an acquired tufted angioma of the eyelids.4 Tenderness, hypertrichosis, and induration are useful signs to clinically differentiate tufted angioma from haemangioma. Other differentials include Kaposi sarcoma, eyelid angiosarcomas and varix. Kaposi sarcoma relates closely with the immune status of the patient and is considered as an auto-immune disease syndrome-defining disease by the World Health Organisation.5 The eyelid involvement has a nodular, elevated appearance and precedes in most cases visceral involvement. Cutaneous angiosarcomas of eyelid are very rare and present as purple coloured maculopapular lesions, suggesting a vascular origin in patients over 55 years of age.6 Varix of eyelid has an associated increase in the size of the lesion with strenuous activity like stooping or Valsalva manoeuvre.7
Basal cell carcinoma arising within a longstanding hemangioma

A 75-year-old man presented to the dermatology clinic for a full-body skin examination. Upon examination, the provider noted a well-circumscribed, 5 mm red papule on the left lower eyelid (Figure 1a). The patient reported that the lesion had been present for over 10 years, which was confirmed by chart review showing diagnosis as a benign angioma. Upon closer inspection utilizing dermoscopy, the lesion was composed of a central lobular vascular proliferation consistent with a benign angioma. However, on the periphery, arborizing telangiectasias in a milky pink stroma were noted, raising suspicion for basal cell carcinoma (Figure 1b). Following a shave biopsy, histopathology showed nested aggregates of basaloid cells with peripheral palisading within the dermis consistent with basal cell carcinoma. Of note, dilated ectatic lobular collections of blood vessels were also noted consistent with an angioma, leading to the diagnosis of a basal cell carcinoma arising within a benign angioma (Figure 2). The tumor was removed after one stage of Mohs surgery.
