Squamous cell carcinoma (SCC) may be the second many cutaneous malignancy following basal cell carcinoma (BCC) with raising incidence. after basal cell carcinoma (BCC) with raising incidence.[1] It could present in a number of morphologies including a keratinizing nodule. Conventionally, SCC is certainly diagnosed and in the watch of nodule being a scientific manifestation medically, it can show up comparable to nodular BCC, atypical fibroxanthoma, sclerosing liposarcoma, and desmoplastic melanoma. Healing and Prognostic implications will vary in every these circumstances, and therefore, their distinction turns into essential.[2] Trichoscopy (dermoscopy of locks SAHA supplier and head) improves the diagnostic accuracy for melanocytic and nonmelanocytic pigmented lesions in comparison to inspection using the unaided eyesight. It enhances the diagnostic precision in pigmented skin damage greatly.[3,4] Recently, research show that in addition, it supports the diagnosis of nonpigmented keratinizing skin damage including actinic keratosis and Bowen’s disease.[5,6] However, there is certainly paucity of literature in trichoscopy of SCC from Indian viewpoint. Thus, this full case sets out to spell it out the trichoscopic patterns in SCC in brown skin. This is actually the initial case reported from Indian situation. CASE Survey A 56-year-old girl presented with epidermis lesion within the vertex from the head for 5 years. There is a past history of occasional bleeding in the lesion upon combing hair. There is no past history of trauma prior to the appearance of lesion. On detailed evaluation, there is an indurated nodule calculating 7 cm 5 cm. It had been epidermis to erythematous in color. It had been attached to root structures. Little ulcer of size 1.5 cm 1.5 cm was found [Figure 1]. Systemic evaluation was unremarkable. Hematological and biochemical analyses had been normal. Trichoscopy with nonpolarizing and polarizing lighting with 10 magnification was IL6R performed. It confirmed white structureless areas on red background, atypical vessels, radially arranged hairpin vessels, and hemorrhage [Figures ?[Figures22C4]. Skin biopsy was carried out using 4 mm punch and sent for histopathology. It showed atypical cells in small clusters, cords, and trabeculae with nuclear hyperchromasia, pleomorphism, and occasional mitosis suggestive of SCC [Figures ?[Figures55 and ?and6].6]. The patient was referred to oncology department SAHA supplier for further management.

There are certain dermoscopic criteria to diagnose SCC explained in literature. These criteria are based on patterns such as hemorrhage, white structureless areas, keratin crusts, white collarette, white pearls, and white circles and also around the morphology of vessels and their arrangement. Keratoacanthoma and SCC show almost same dermoscopic patterns with very few patterns in higher or lower frequencies.[2] In this study, white structureless areas were arranged in diffuse aswell as speckled design. Light structureless areas match either hyperkeratosis and collagen or acanthosis fibres in the dermis.
