    Merkel cell carcinoma (MCC) is a rare tumor that arises from mechanoreceptor Merkel cells. Ultraviolet exposure, immunosuppression and Merkel cell polyoma virus play a significant role in tumor pathogenesis. Although it typically presents as an initially indolent growing, painless solitary lesion, the course of MCC may be aggressive due to the nodal invasion, distant metastasis and high recurrence rates. We presented a case of MCC with a background history of rheumatoid arthritis treated with immunosuppressive therapy for many years who had necrotizing granulomatous lymphadenitis.

    ackground:: Pigmented purpuric dermatosis is a chronic skin disorder of unknown aetiology characterised by symmetrical petechial and pigmented macules, often confined to the lower limbs. The aetiology of pigmented purpuric dermatosis is unknown. Dermatoscopy is a non-invasive diagnostic technique that allows the visualisation of morphological features invisible to the naked eye; it combines a method that renders the corneal layer of the skin translucent with an optical system that magnifies the image projected onto the retina. Objectives:: The aim of this study is to investigate the dermatoscopic findings of pigmented purpuric dermatosis. Methods:: This study enrolled patients diagnosed histopathologically with pigmented purpuric dermatosis who had dermatoscopic records. We reviewed the dermatoscopic images of PPD patients who attended the outpatient clinic in the Istanbul Dermatovenereology Department at the Bezmialem Vakıf University Medical Faculty. Results:: Dermatoscopy showed: coppery-red pigmentation (97%, n = 31) in the background, a brown network (34%, n = 11), linear vessels (22%, n = 7), round to oval red dots, globules, and patches (69%, n = 22; 75%, n = 24; 34%, n = 11; respectively), brown globules (26%, n = 8) and dots (53%, n = 17), linear brown lines (22%, n = 7), and follicular openings (13%, n = 4). Conclusion:: To our knowledge, this is the first study to report the dermatoscopy of pigmented purpuric dermatosis. In our opinion, dermatoscopy can be useful in the diagnosis of pigmented purpuric dermatosis.

    A Rare Confusing Nevus Variant: Meyerson Nevus
    (2018-01-01T00:00:00Z) YILDIZ, PELİN; KÜÇÜK, ÖZLEM SU; DİZMAN, DİDEM; Tosuner, Zeynep; ARICI, Belfin Nur; DEVECİ, Uğur; DEMİRKESEN, Cüyan; YILDIZ, PELİN; SU KÜÇÜK, ÖZLEM; TOSUNER, ZEYNEP; DİZMAN, DİDEM
    Meyerson nevus is a rare benign entity described by Meyerson et al in 1971 as a melanocytic nevus surrounded by inflammatory, eczematous eruption that resolves spontaneously or by topical steriod therapy (fluticasone propionate, Abdi Ibrahim Ilac San. ve Tic. A.S., Istanbul), but the nevus persists. This entity is not well known and there is limited information in the literature. Since the lesion may develop suspicion for malignancy, it is important to keep this entity in mind. In this article we present three Meyerson nevi, two of which belong to one patient.
