Sir,

Lichen planus is a chronic inflammatory mucocutaneous disease. [1] The prevalence in the general population is reported to be 0.1-3%. [2] It is most common in the fourth decade of life and has a female-to-male prevalence ratio of 3:2. [1] To the best of our knowledge, there is only one case of cervical lichen planus reported so far. [3]

A 28-year-old woman with a history of cutaneous lichen planus for eight years presented to the gynecologist for a routine examination. She was asymptomatic and had no co-morbidities. She had been treated with oral prednisolone during the periods of exacerbation. There was no history of use of other drugs or intrauterine contraceptive devices prior to onset of lesions. She had undergone three sessions of cryotherapy at 4-week intervals with the diagnosis of cervicitis before being referred to our center; however there was no clinical response. At presentation, her skin lesions had relapsed. On gynecological examination, there was a whitish ulceration measuring 1.5 × 1 cm in the posterior lip of cervix at the 5 o'clock position. Her vulvovaginal examination was normal [Figure 1]. The cervical smear showed non-specific inflammation. Mucocutaneous examination revealed generalized violaceous polygonal flat-topped papules on her trunk and extremities suggestive of classical lichen planus [Figure 2].

Histopathological examination of the erosion revealed saw-toothed rete ridges in some areas of the epidermis and a band like lymphocytic infiltrate in the dermis with basal cell degeneration confirming the diagnosis of erosive lichen planus. There was no evidence of dysplasia in the epithelium. [Figure 3]. Laboratory  tests for human papilloma virus (HPV) and hepatitis C virus (HCV) infection were negative. Based on previous reports in the literature on safety and efficacy of methotrexate in lichen planus, including the vulvovaginal type, [4] we decided to treat her with oral methotrexate. After a 5 mg test dose, she was treated with oral methotrexate, 10 mg once weekly. After 3 months, there was a significant improvement in cutaneous lesions with a partial response in the cervical lesion [Figure 1] and [Figure 2].

Vulvovaginal involvement is seen in approximately 57% of women with oral lichen planus while concomitant skin involvement is reported among 15% of the patients. [5] Another study also noted that vulvar lichen planus is more frequently associated with other mucosal lesions than skin lesions. [6] However, our patient presented with an erosive cervical lesion with no evidence of oral or external genital lesions. Oral disease is associated with several potential risk factors such as genetic predisposition, [1] infections, [3],[5] human papilloma virus [3],[6] and hepatitis C virus [5],[6] Since human papilloma virus infection is common in the cervix, [3] it is necessary to evaluate its role in cases of cervical lichen planus. Low-risk types of human papilloma virus were detected in a proportion of patients with vulvar lichen planus. [6]

Malignant transformation of cutaneous lesions of lichen planus has been reported to be less than 1%, [3] while the risk rate reported for oral lesions ranges from 0.4-5% in different studies. [3],[5],[6] There are few reports of squamous cell carcinoma in vulvar lichen planus. [3],[6] There is no information on the risk of malignant transformation in cervical lichen planus.

Examination of the cervix in women with generalized lichen planus will help us know how frequently this site is affected.
