Premalignant Progression

Actinic keratoses form as rough, scaly plaques on sun-exposed areas; they can be an important step in premalignant progression to squamous cell cancer of the skin. Currently, pharmacological treatments consist of topical immunomodulatory agents with poor side effect profiles. Use of honey has been common in both ancient and modern medicine, where it is now a key therapy in the management of wound healing. In vitro studies show the New Zealand native Kanuka honey to have immunomodulatory and antimitotic effects, with recent evidence suggesting efficacy of topical application in a variety of dermatological contexts, including rosacea and psoriasis. Here, we present a case report of a 66-year-old gentleman with an actinic keratosis on his hand, which had been present for years. Regular application of Kanuka honey over three months resulted in remission immediately following the treatment period with no signs of recurrence at nine months.

Verrucous carcinoma (VC) is a rare subtype of squamous cell carcinoma that commonly occurs in the oral cavity. However, VC of the facial skin is relatively rare. We report a case of a 91-year-old woman with VC of the facial skin in the left zygoma area. She was diagnosed with actinic keratosis (4 × 3 cm) of the same site approximately 12 years previously, but declined further treatment. The mass was excised with a minimum of 0.4 cm from gross margins with the result of free from tumor of all margins by frozen section, allowing for primary closure after skin undermining. Basal resection was performed in the preplatysmal plane. The diagnosis of VC was confirmed by histopathological examination. Postoperatively, the wound healed without incident and with no signs of facial nerve injury. To our knowledge, this is the first reported case of VC of facial skin arising from actinic keratosis.

Pigmented Actinic Keratosis

Four types of facial pigmented skin lesions (FPSLs) constitute diagnostic challenge to dermatologists; early seborrheic keratosis (SK), pigmented actinic keratosis (AK), lentigo maligna (LM), and solar lentigo (SL). A retrospective analysis of dermoscopic images of histopathologically diagnosed clinically-challenging 64 flat FPSLs was conducted to establish the dermoscopic findings corresponding to each of SK, pigmented AK, LM, and SL. Four main dermoscopic features were evaluated: sharp demarcation, pigment pattern, follicular/epidermal pattern, and vascular pattern. In SK, the most specific dermoscopic features are follicular/epidermal pattern (cerebriform pattern; 100% of lesions, milia-like cysts; 50%, and comedo-like openings; 37.50%), and sharp demarcation (54.17%). AK and LM showed a composite characteristic pattern named “strawberry pattern” in 41.18% and 25% of lesions respectively, characterized by a background erythema and red pseudo-network, associated with prominent follicular openings surrounded by a white halo. However, in LM “strawberry pattern” is widely covered by psewdonetwork (87.5%), homogenous structureless pigmentation (75%) and other vascular patterns. In SL, structureless homogenous pigmentation was recognized in all lesions (100%). From the above mentioned data, we developed an algorithm to guide in dermoscopic features of FPSLs.
