Desmoplastic trichoepithelioma is a rare benign adnexal tumor. Although it is a benign lesion, patients often want to treat it due to cosmetic concerns when it occurs in an easily visible site. For our two cases, topical 5% imiquimod was an attractive treatment option as it is applied by the patients themselves and it has minimal side effects, including leaving no scar. However, the lesions recurred after clinical remission. To the best of our knowledge, this is the only report on utilizing imiquimod to treat a benign adnexal tumor, and especially desmoplastic trichoepithelioma.

Keratoacanthoma (KA) is a benign epidermal tumor, characterized by rapid and abundant growth, a tendency toward spontaneous regression and histopathologic similarity to squamous cell carcinoma (SCC). Because KA can be easily misdiagnosed as SCC, surgery is considered the treatment of choice. Recently, regression of KAs following application of 5% imiquimod cream (Aldara(R)) has been reported. We present 4 cases of KA treated with topical imiquimod, applied 3 to 4 times a week. Obvious improvement was observed after 4 to 6 weeks of application and the lesions were almost cleared leaving scars after 9 to 11 weeks. These results show that topical imiquimod can be an effective option for the conservative management of KA as previously reported. We also suggest that lesions treated with imiquimod cream should be considered for biopsy to judge histopathological remission after 5 to 8 weeks of application to shorten the duration of the treatment.

Infantile hemangiomas are the most common benign tumors of infancy and they can occur on any part of the body. However, their presentation as a perianal ulcer prior to the development of a clinical hemangioma is extremely rare. A 5-week-old girl presented with painful ulcerated lesions on the perianal area, which developed about 10 days after her birth. Histopathologic examination showed the proliferation of dilated vessels in the upper dermis. The patient was treated with combined approach using topical steroid, 5% imiquimod cream and triamcinolone intralesional injection. Clinical improvement was observed. We herein report on a case of infantile hemangioma that presented with perianal ulcers.

Imiquimod is a new immunomodulating agent with antitumor and antiviral properties that has been shown to be clinically effective in various kinds of skin diseases, including precancerous dermatoses. Erythroplasia of Queyrat is a carcinoma in situ that mainly occurs on the glans penis. There are several non-invasive treatment options for erythroplasia of Queyrat such as photodynamic therapy, cryosurgery and applying various kinds of topical agents. We now report a case of typical erythroplasia of Queyrat on glans penis associated with human papillomavirus type 16 infection that was treated by imiquimod 5% cream and the subsequent excision of an imiquimod-resistant penile lesion.

BACKGROUND: Although molluscum contagiosum (MC) resolves spontaneously, there are several reasons to treat this dermatological disorder. OBJECTIVE: To evaluate the safety and efficacy of 5% imiquimod cream versus 10% potassium hydroxide (KOH) solution in treating MC, and to propose the mechanism of cure by observing the histological findings. METHODS: Imiquimod or KOH were applied by the patient or a parent 3 days per week until all lesions cleared. The number of MC lesions was counted and side effects were evaluated at 5 points during the treatment (the initial visit, week 2, week 4, week 8, and week 12). Histological changes were compared between 2 patients of each group, before and after the 2 weeks of application. RESULTS: In both group, the mean lesion counts decreased all through to week 12, and the reduction in number of lesions were statistically significant in both groups (p <0.005). Over 40% of each group developed local side effects, and no systemic side effects were noted in either group. Before treatment, histological findings showed little or no dermal infiltrates. After treatment, specimens showed dense lymphocytic infiltrates, especially T cells, around the lesions which had resolved. CONCLUSION: Both 10% KOH solution and 5% imiquimod cream are effective and safe treatment of MC.

Bowen's disease is an in situ squamous cell carcinoma. It usually occurs as a solitary lesion, but it sometimes occurs as multiple lesions. There are many therapeutic options for Bowen's disease. Among the therapies, some methods could be used for multiple lesions. However, the choice of treatment is important because the healing and success rates may vary according to the body site. A 60-year-old female patient presented with multiple erythematous plaques. The diagnosis of multiple Bowen's disease was based on the clinical and histologic features. There were too many suspicious lesions for one local treatment, so we treated the lesions with 5% imiquimod cream and oral acitretin. The imiquimod cream was applied every other day for 33 weeks and oral acitretin was prescribed for 13 weeks. After this treatment, most of the lesions were improved. The follow up biopsy showed only scar tissue. This case demonstrates that a combination of imiquimod cream and oral acitretin might be an alternative treatment option for multiple Bowen's disease lesions.

BACKGROUND: Extramammary Paget disease (EMPD) is an uncommon malignant neoplasm affecting apocrine gland-bearing skin which usually occurs in the anogenital area of patients older than 50 years. Although Mohs micrographic surgery (MMS) is recommended for the treatment of EMPD, wide local excision has also been performed by many other surgeons including dermatosurgeons. However, the extent of an adequate resection margin is still under debate. OBJECTIVE: The efficacy of minimal surgical therapy consisting of a wide excision combined with preoperative multiple scouting biopsies and postoperative topical imiquimod was investigated for the treatment of EMPD in Korean patients. METHODS: Between 2006 and 2012, 10 patients with primary EMPD were treated with wide surgical excision, with a surgical margin of less than 2.5 cm. Multiple preoperative scouting biopsies and postoperative topical imiquimod were also performed to delineate the lesional boundaries and to reduce the recurrence rate. RESULTS: During the 6-year follow-up period, complications and recurrences were not observed. CONCLUSION: Minimal surgical therapy may be an effective alternative when MMS is unavailable.

Journal of the Korean Association of Pediatric Surgeons 2010;16(1):32-36
Condyloma acuminatum is an uncommon disease but there is an increased incidence reported in recent years in prepubertal children. Anal and perianal condyloma accuminatum in children may suggest sexual abuse and treatment should include the thorough social evaluation as well as medical treatment. A 25 month old girl presented with multiple sessile nodules around her anal and perianal area, Biopsy confirmed the diagnosis of condyloma accuminatum. There was no definite evidence of sexual abuse, but her father had condyloma accuminatum involving his penis. The patient's lesions were excised totally. At three week follow up there was no anal stricture but there were newly developed small lesions around perianal area. Imiquimod onit was applied for 2 weeks and the recurred lesion disappeared completely. At postoperative 5 month, the operative area was fully epithelialized without recurrence.
