“…Therefore, dermoscopy and RCM can provide valuable noninvasive clues for the diagnosis and follow-up of patients with EPC. 2 Our case highlights not only the aggressive behavior of relapsing EPC but also the novel cytomorphologic features under RCM. These findings should be further explored for possible presurgical assessment of EPC considering its high local recurrence rate.…”

A 63-year-old woman presented with an exophytic polypoid tumor on her left arm, adjacent to a previous scar. An eccrine porocarcinoma (EPC) had been excised 10 months before presentation (Fig 1, A). DERMOSCOPIC APPEARANCELobular aggregates were seen with a diffuse arrangement of focused and unfocused polymorphous (ie, linear-irregular, arboriform, and coiled) vessels within, surrounded by a white-pink halo; ulceration was also noted (Fig 1, B). Clinical and dermoscopic presentations of relapsing eccrine porocarcinoma. A, A poorly defined exophytic tumor with multiple clustered pink papules on the left arm, 3 cm in maximum diameter, adjacent to a previous scar; few satellite papules are seen. B, Dermoscopy reveals a lobular arrangement of multiple polymorphic vessels (ie, linear-irregular, arboriform, and coiled) surrounded by peripheral white-pink halos; ulceration is also seen.

“… 1 As it might simulate malignant tumors like basal cell carcinoma due to nonspecific clinical appearance, we highlight the potential usefulness for dermoscopy and second-level noninvasive techniques, including reflectance confocal microscopic examination. 2 Dermoscopy revealed an important distribution and combination of colors: yellow, white, and red in correlation with sebaceous differentiation, fibrosis of the stroma, and increased vascularization, respectively. It also showed different vascular morphologies, possibly resulting from the patterns of tumor growth both in the epidermis and dermis.…”

An 85-year-old woman presented with a 2-year history of a slow-growing, asymptomatic pedunculated flesh-colored papule on the left arm (Fig 1). The patient denied any history of skin cancer. DERMOSCOPIC APPEARANCEDermoscopy revealed sharply focused arborizing and linear-irregular polymorphic vessels. Some of them were seen blurred within the pink structureless areas, where shiny-white strands under polarized light and orange or brownish erosions were additional features (Fig 2).

Dear Editor, Poroma is a benign neoplasm, in which tumor cells differentiate towards poroid and cuticular cells of acrosyringium.A 79-year-old woman (case 1) presented with an 18 mm 9 14 mm, bulb-shaped, light pink semipedunculated nodule with ring-like blackish macules on her left temporal region ( Fig. 1a). A 58-year-old man (case 2) exhibited a similar 12 mm 9 12 mm, semipedunculated nubby nodule on his right temporal region (Fig. 1a). Dermoscopic examination revealed thick vessels and large blue-gray ovoid nests in both cases (a) (b) (c) (d) (e) Figure 1. (a) Clinical images of cases 1 (left) and 2 (right). (b) Dermoscopic images of cases 1 (left) and 2 (right). Arrows indicate arborizing-like vessels; arrowheads, blue-gray ovoid nests. (c) Reflectance confocal microscopy of case 2 shows congested cells (white arrow) with small black holes (white arrowheads) without a palisading pattern at the periphery of the tumor nests. (d)Histopathological images of cases 1 (left) and 2 (right) (hematoxylin-eosin). In more detail, the features of two subtypes of the tumor, poroma and dermal duct tumor, are observed in case 2. Melanin granules are found mainly in the upper to middle dermis forming clusters, probably reflected in the dermoscopic structures of relatively smooth and homogeneous blue-gray ovoid nests shown in (b). Arrows, poroid cells; arrowheads, cuticular cells (bars, 100 lm). (e) Dermoscopic images of the nodules alongside the noses of the other two patients, cases 3 (left) and 4 (right). Both of these nodules were histopathologically demonstrated to be typical nodular basal cell carcinoma (data not shown). Arrows, arborizing vessels; arrowheads, blue-gray ovoid nests.
