He noted fatigue, weakness, ankle swelling, abdominal fullness, headaches, lapses in memory, and dysphasia. On physical examination, he had thin and atrophied upper extremities and central obesity, as well as nonblanching red to purple macules on the lower abdomen and ecchymosis on bilateral arms. The patient denied the use of any corticosteroids. Lab workup showed an abnormally high post-dexamethasone cortisol level, which raised suspicion for Cushing syndrome. Further inquiry into the patient's medication and supplement history revealed that he was consuming Artri King, a supplement marketed for the treatment of joint pain and arthritis. Artri King can lead to numerous dermatological manifestations akin to endogenous Cushing syndrome such as thin skin, easy bruising, and purple striae. This case illustrates the potential risks of over-the-counter dietary supplements, which often circumvent the strict Food and Drug Administration regulations applied to prescription medications, posing significant health hazards to users. There is critical need for transparency and regulation of supplements.","PeriodicalId":11040,"journal":{"name":"Dermatology online journal","volume":"31 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145136827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Definitive diagnosis is established by histopathology which reveals the presence of colloid in dermal papillae. Photo-exposed areas are the most frequently involved sites and include dorsa of hands, neck, and ears. We present an adult man with an outdoor occupation who had longstanding chronic actinic dermatitis. For one and a half years he had been developing skin colored to slightly erythematous papules and nodules on his face, anterior neck, and dorsal aspect of the hands, symmetrically. These discrete lesions arose on the background of his eczematous sun exposed skin. Skin biopsy for histopathology of these papules showed deposition of amorphous colloid material in the dermal papillae with an uninvolved Grenz zone along with dermal solar elastoses. The coexistence of colloid milium with chronic actinic dermatitis in the same patient has not been previously reported in the medical literature even though both conditions are precipitated by chronic sun exposure. Similarly, such extensive lesions of colloid milium have rarely been reported and we ascribe this to his profession, compelling him to spend numerous hours in the sun every day.","PeriodicalId":11040,"journal":{"name":"Dermatology online journal","volume":"31 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145136847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reports a new case involving multiple melanoma lesions in tattoo pigment, alongside a systematic review of past cases. Our objectives were to evaluate the potential for delayed diagnosis in patients with melanoma lesions in tattoo pigment and its impact on prognosis, comparing tumor characteristics with large-scale melanoma studies. A systematic review was conducted using PubMed and Ovid MEDLINE. Included studies were English-language reports of melanoma lesions in tattoo pigment, identifying new cases via case reports/series. Independent review and discussion resolved discrepancies. The review yielded 37 articles with 42 reports of melanoma lesions in tattoo pigment, totaling 43 cases. Of these, 35 were invasive, with mean and median Breslow thickness of 2.49mm and 0.9mm, respectively, which is higher than in large-scale studies. Patients also had a higher incidence of invasive lesions at diagnosis. The increased Breslow depth and risk of dermal invasion suggest a higher risk for delayed diagnosis and worse prognosis in melanoma arising in tattoo pigment. Further analysis of dermatoscopic differences is needed to improve diagnostic guidelines and avoid delayed diagnosis.","PeriodicalId":11040,"journal":{"name":"Dermatology online journal","volume":"31 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145136855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plasmacytoid dendritic cells can resemble lymphocytes and histiocytes morphologically and immunophenotypically. Mature plasmacytoid dendritic cell proliferation may therefore go unrecognized if the diagnosis is not suspected and appropriate stains for plasmacytoid dendritic cells are not performed. Herein, we present a case of mature plasmacytoid dendritic cell proliferation masquerading clinically and histologically as histiocytoid Sweet syndrome. The patient, who had previously been diagnosed with mature plasmacytoid dendritic cell proliferation that presented as pink, edematous, pruritic papules and plaques, had initially resolved following induction chemotherapy for acute myelomonocytic leukemia. However, he presented later with indurated purpuric plaques on the trunk within weeks of receiving filgrastim for neutropenia. Biopsies demonstrated marked dermal edema, interstitial, superficial, and deep infiltrate with histiocytoid appearing cells concerning for histiocytoid Sweet syndrome. Further work-up demonstrated that the infiltrate was predominantly composed of CD3-, CD4+, CD34-, CD123+, CD56-, CD68-, myeloperoxidase negative mononuclear cells consistent with mature plasmacytoid dendritic cell proliferation. This case demonstrates that MPDCP should be considered in the differential diagnosis of eruptions that clinically and histologically look like histiocytoid Sweet syndrome but stain negatively for myeloperoxidase.","PeriodicalId":11040,"journal":{"name":"Dermatology online journal","volume":"31 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145136818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
