Acné queloideo de la nuca: excelente respuesta al tratamiento con imiquimod 5% / Keloid acne of the nape: excellent response to treatment with imiquimod 5%

El acné queloideo de la nuca (AKN) o foliculitis esclerosante es un proceso inflamatorio crónico del folículo piloso en la región de la nuca. Su incidencia es baja y su etiología desconocida. Afecta con mayor frecuencia a hombres de mediana edad y de raza negra. A lo largo del tiempo se han utilizado diferentes modalidades terapéuticas con resultados variables. Presentamos el caso de un paciente con AKN que mostró una excelente respuesta al uso diario de imiquimod 5% tópico durante ocho semanas

Keloid acne of the neck (AKN) or sclerosing folliculitis of the nape of the neck is a chronic inflammatory process of the nape region. Its incidence is low and its etiology is unknown. It mainly affects brown-black males in middle age. Different treatment modalities have been used with different responses. We present the case of a patient with AKN who presented an excellent response to the daily use of topical imiquimod 5% for eight weeks

Recurrent Paget’s disease of the vulva in a split-thickness graft / Philippine Journal of Obstetrics and Gynecology

@#Extramammary Paget’s disease (EMPD) of the vulva is a rare vulvar neoplasm but commonly arises during the postmenopausal period. Intraepithelial Paget’s disease may persist for prolonged periods without demonstrating invasion but with high rates of recurrence. Appearance of Paget’s disease in a split-thickness skin graft, is associated with an occurrence outside the grafted area. It demonstrates retrodissemination as the pathologic process hypothesized in the spread of the disease within the skin via lymphatics and vessels creating tissue bridges between sites of involvement. We present a case of an 81-year-old female, the patient came in for complaints of vulvar pruritus beginning at the left inguinal area three years prior to her diagnosis. She consulted with a dermatologist and was initially treated with steroids and emollients. Persistence of symptoms and enlargement of the lesion prompted a vulvar punch biopsy which showed Paget’s disease and referral to the Gynecologic Oncology service. Wide local excision with split-thickness skin grafting was performed. However, one year after her surgery, patient noted vulvar pain and palpable vulvar lesions. Biopsy was done which showed Extramammary Paget’s Disease recurrence. Patient underwent repeat wide local excision with frozen section, and split-thickness skin grafting. With the aid of frozen section, the intraepithelial involvement was noted to spread beyond the grossly apparent lesion. After 6 months post re-excision, patient noted vulvar pruritus and palpable vulvar lesions. Biopsy was done which showed Extramammary Paget’s Disease recurrence. Due to the proximity of the lesion to the sphincter and need for a colostomy, the patient did not consent for re-excision. Imiquimod 5% was chosen as the mode of treatment. The challenges of interventions are to remove or treat disease that may not be visible, without overtreatment and to minimize morbidity from radical surgery. Surgery remains the primary management for EMPD of the vulva. Imiquimod 5% can be used in recurrences. Despite the advances in the knowledge and management of vulvar Paget’s disease the high rate of recurrent disease remains a challenge for optimal management and would require frequent and long-term follow-up.

Treatment of Keratoacanthoma with 5% Imiquimod Cream

Keratoacanthoma is a rapidly growing tumor that histologically resembles squamous cell carcinoma. Surgical excision is a desirable therapeutic option, but several other treatment modalities are available. We report on two cases of keratoacanthoma that were treated with imiquimod 5% cream. Imiquimod was applied daily for the first 6 or 7 days, and then reduced to alternate days according to the tolerance and erythema severity of the patient. In both patients, the tumors fully regressed after five weeks of treatment.
