Diagnostic Considerations

Lymphangioma circumscriptum may resemble warts, metastatic carcinoma of the skin, lymphangiectasis, herpes simplex, and herpes zoster. [3]  Metastasis of a papillary thyroid microcarcinoma may appear as a cystic lymphangioma of the neck. [24]

Other cysts and soft subcutaneous masses should be considered. Oral and cutaneous lymphangioma-like Kaposi sarcoma may require distinction. [25]

Occasionally, acquired lymphangioma circumscriptum of the vulva may mimic genital warts, appearing as verrucous plaques, [26, 27, 28, 29] although these common viral infections may occur with the lymphangiomas and display overlapping clinical features. [30] Resulting from interference in the lymph drainage, acquired lymphangioma circumscriptum is often related linked to oncological surgical procedures.

Genital lymphangiomas may be complicated by cellulitis. [1]

Cystic hygroma can be associated with the following congenital disorders:

Patients with cystic hygroma should undergo cytogenetic analysis for chromosomal aneuploidy. Parents should receive genetic counseling because aneuploidic conditions can recur in subsequent pregnancies. [33]
