Abstract

Background: Primary cutaneous lymphomas are neoplasms of the immune system with a distinct tropism for the skin and an absence of extracutaneous manifestations at the time of diagnosis. Studies focusing on cutaneous lymphomas in children and adolescents remain scarce and often do not encompass the rare subtypes. Objectives: To address this knowledge gap by describing the clinical, histological and molecular characteristics of a large group of paediatric patients affected by primary cutaneous lymphoma. We also provided the Paediatric Primary Cutaneous Lymphoma Atlas that illustrates the clinicopathological spectrum of observed presentations, in the hope of supporting other physicians in the diagnostic process. Methods: Retrospective chart review of paediatric patients diagnosed with primary cutaneous lymphomas between 1980 and 2022 at the Paediatric Dermatology Unit of Fondazione IRCCS Ca′ Granda Ospedale Maggiore Policlinico, Milan. Results: A total of 101 patients (58 males, 43 females) met the inclusion criteria. The most common subtypes were lymphomatoid papulosis (n = 48) and mycosis fungoides (n = 31). These were followed by primary cutaneous CD4+ small/medium T‐cell lymphoproliferative disorders (n = 7), primary cutaneous anaplastic large‐cell lymphomas (n = 5), primary cutaneous marginal zone B‐cell lymphomas (n = 3), primary cutaneous follicle centre lymphomas (n = 2), subcutaneous panniculitis‐like T‐cell lymphomas (n = 2), primary cutaneous peripheral T‐cell lymphoma not otherwise specified (n = 1), primary cutaneous precursor B‐lymphoblastic lymphoma (n = 1) and Sézary syndrome (n = 1). Clinical follow‐up data covering a median of 70.8 months (range 1–324) were available for 74 patients, of whom three died due to cutaneous lymphoma. Conclusions: Our findings shed light on the peculiar aspects and long‐term outcomes of paediatric cutaneous lymphomas, particularly emphasizing their distinctive features in comparison to their adult counterparts and exploring the less common subtypes. Further larger‐scale studies are warranted to better characterize these entities and to achieve a more rapid and accurate diagnosis. [ABSTRACT FROM AUTHOR]

Abstract

Background Lymphomatoid papulosis (LyP) is a rare cutaneous T-cell lymphoproliferative disorder. Comprehensive data on LyP in the paediatric population are scarce. Objectives To characterize the epidemiological, clinical, histopathological and prognostic features of paediatric LyP. Methods This was a retrospective multicentre international cohort study that included 87 children and adolescents with LyP diagnosed between 1998 and 2022. Patients aged ≤ 18 years at disease onset were included. LyP diagnosis was made in each centre, based on clinicopathological correlation. Results Eighty-seven patients from 12 centres were included. Mean age at disease onset was 7.0 years (range 3 months–18 years) with a male to female ratio of 2 : 1. Mean time between the onset of the first cutaneous lesions and diagnosis was 1.3 years (range 0–14). Initial misdiagnosis concerned 26% of patients. LyP was most often misdiagnosed as pityriasis lichenoides et varioliformis acuta, insect bites or mollusca contagiosa. Erythematous papules or papulonodules were the most frequent clinical presentation. Pruritus was specifically mentioned in 21% of patients. The main histological subtype was type A in 55% of cases. When analysed, monoclonal T-cell receptor rearrangement was found in 77% of skin biopsies. The overall survival rate was 100%, with follow-up at 5 years available for 33 patients and at 15 years for 8 patients. Associated haematological malignancy (HM) occurred in 10% of cases (n = 7/73), including four patients with mycosis fungoides, one with primary cutaneous anaplastic large cell lymphoma (ALCL), one with systemic ALCL and one with acute myeloid leukaemia. If we compared incidence rates of cancer with the world population aged 0–19 years from 2001 to 2010, we estimated a significantly higher risk of associated malignancy in general, occurring before the age of 19 years (incidence rate ratio 87.49, 95% confidence interval 86.01–88.99). Conclusions We report epidemiological data from a large international cohort of children and adolescents with LyP. Overall, the disease prognosis is good, with excellent survival rates for all patients. Owing to an increased risk of associated HM, long-term follow-up should be recommended for patients with LyP.

Abstract

This article discusses a rare condition called pigmentary lines of the newborn, which is characterized by the presence of thin hyperpigmented lines on the abdomen, back, and limbs of infants. The condition is more commonly seen in male infants with darker skin. It is a benign and transitory condition that resolves spontaneously between 2 and 8 months of age. The diagnosis is based on clinical examination, as there are no specific laboratory or histopathologic findings. Treatment is not necessary, and the condition does not have any extracutaneous associations. [Extracted from the article]
