“…While some experts categorize them in certain cases as precursor lymphoid dyscrasias of cutaneous lymphomas, others suggest that they could be considered an atypical variant of MF. [3][4][5] In clinical cases showing suggestive signs of PPD with a tendency to evolve towards MF, a broader than usual cutaneous dissemination is observed, with larger lesions that tend to coalesce. These lesions are also lichenoid, accompanied by itching, and persist for at least one year.…”

This case report explores the progression of cutaneous lymphoid dyscrasia to a lymphoma in a 13-year-old boy with pityriasis lichenoides chronica and lichenoid pigmented purpuric dermatitis, the latter evolving into mycosis fungoides. We highlight some of the crucial clinical and histological characteristics to differentiate between these entities. Early identification of this progression is critical not only for preventing further lymphoma development but also for initiating prompt therapy.

“…PMF diagnosis in the early stages is challenging as it may closely mimic inflammatory skin diseases, including pigmented purpuric dermatosis (PPD). 3 Pigmented purpuric dermatosis comprises a group of inflammatory skin disorders expressing as petechial and pigmented macules and plaques. 4,5 PPD has been conventionally divided into five clinical types, which in order of prevalence are as follows: Schamberg's disease, eczematoid purpura of Doucas and Kapetanakis, lichen aureus, Majocchi's disease and Gougerot-Blum purpura.…”

Pigmented purpuric dermatoses versus purpuric mycosis fungoides: Clinicopathologic similarities and new insights into dermoscopic features

et al. 2021

Background:The diagnosis of purpuric mycosis fungoides (PMF) is often challenging to be clinically differentiated from inflammatory diseases such as pigmented purpuric dermatosis (PPD). Dermoscopy as a non-invasive method can be employed for the visualisation of features invisible to the naked eye.Objectives: This study aimed to survey the dermoscopic findings of PMF in comparison with PPD.Methods: Forty-one patients with an established diagnosis of PMF (n = 28) and PPD (n = 13) were prospectively recruited. Dermoscopic images were taken by FotoFinder Medicam 1000 (FotoFinder Systems GmbH, Bad Birnbach, Germany).Results: Characteristic dermoscopic patterns consisting of fine short linear vessels (35.7%, P = 0.017) and spermatozoa-like structures (50%, P = 0.014) were found to be significantly more common in PMF lesions, while PPD lesions were typified by erythematous globules (76.9%, P = 0.01), in the background colour of dull red (61.5%, P = 0.01) and reticular pigmentation (61.5%, P = 0.044).Conclusions: This study showed the usefulness of dermoscopy for the diagnosis of PMF and PPD cases. Studies with long-term follow-up are needed to affirm the value of these dermoscopic patterns in the differentiation between the two entities.
