Infiltrative Trichilemmal Carcinoma Treated with 5% Imiquimod Cream

Imiquimod as an adjuvant treatment measure for desmoplastic trichoepithelioma

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.

Non-surgical treatments of primary, non-melanoma eyelid malignancies: a review

The diagnosis and management of periocular cutaneous malignancies are essential components of an ophthalmologist's practice. Skin cancers comprise nearly one-third of newly diagnosed malignancies. Furthermore, the incidence of skin cancer appears to be increasing. Multiple treatment modalities exist for periocular cutaneous malignancy. Surgical extirpation, often with the combined expertise of a Mohs micrographic surgeon, is typically the first line therapy and is often curative in the periocular region, depending on a variety of factors, including tumour histology, specific location, depth of invasion and surgical technique. However, there are instances where a less invasive, non-surgical treatment option is warranted, including patients who are poor surgical risks or those with diffuse disease. The purpose of this article is to review the literature and describe the non-surgical treatment options, indications and efficacies for non-melanoma primary eyelid malignancies.
