A 20-year-old female patient was admitted to our clinic with a complaint of swelling on her toe for 5 months. She had a 7-month history of pregnancy and it was learned that the lesion had grown during pregnancy. No similar lesions were observed in another part of the body. Her medical history and family history were normal. ELISA for HIV was negative. Dermatological examination revealed a pale erythematous papule on the third interdigital region that had a sulcus on it [Figure 1]. Pyogenic granuloma and molluscum contagiosum (MC) were considered and the lesion was totally excised. Histopathological examination revealed intracytoplasmic viral inclusion bodies in keratinocytes [Figure 2].

A pale erythematous papule on the third interdigital region that had a sulcus on itIntracytoplasmic viral inclusion bodies in keratinocytes and acanthotic epidermis (hematoxylin and eosin ×40)MC is a common infection caused by an MC virus.[1] It mainly affects young children, sexually active adults and immunocompromised patients.[2] Umbilicated pearly papules are usually sufficient for diagnosis. MC may spread by autoinoculation, direct contact, towel, or swimming.[13] The most affected sites are the genital region, the axillary and the popliteal fossa. Oral mucosa, conjunctiva, and plantar involvement are rare. The clinical diagnosis of MC infections in atypical localization may be difficult and may be related to human immunodeficiency virus (HIV) infection.[4] Lesions at the base of the foot can be mixed with epidermal cyst, eccrine poroma, verruca, and pyogenic granuloma.[45]In conclusion, we think that pregnancy, which is an immunosuppressive condition, causes the development and growth of MC in interdigital area which is an atypical localization for MC infection.
