Article Synopsis
- - The study investigates primary cutaneous marginal zone lymphoma (PCMZL) by analyzing recurrent cases to determine whether it's a reactive process or a true lymphoma, utilizing data from the French Study Group of Cutaneous Lymphoma (GFELC).
- - Methods included assessing histology, B-cell clonality, and immunophenotype of lesions, revealing that most initial cases were localized, with differences in recurrence times based on location, and certain clonal patterns were more prominent in local recurrences.
- - The findings suggest that assessing immunoglobulin phenotype, particularly IgM and IgD, may be critical for diagnosing PCMZL, as IgM-positive cases tend to lead to more aggressive transformation and poorer prognosis, indicating different biological
Article Synopsis
- - Naevoid basal cell carcinoma syndrome (NBCCS) is a rare genetic condition caused by mutations in the Sonic Hedgehog (SHH) pathway, leading to early development of multiple basal cell carcinomas (BCCs) and related skin tumors like basaloid follicular hamartoma (BFH).
- - A study analyzed 140 skin tumors from NBCCS patients and 140 control BCC tumors to compare their morphological characteristics, finding that BFH was exclusively present in NBCCS patients and had distinct histopathological features.
- - The research indicates that BFH could represent precursors to BCC, as it was identified in up to 24% of the tumors in NBCCS patients, with possible
Background: Mycosis fungoides (MF) usually has an indolent course. However, some patients develop more aggressive disease and few prognostic parameters have been identified. Isolated cases of pustular MF (pMF) suggest an unfavourable prognosis.

- Porocarcinoma is a malignant sweat gland tumor that can develop from benign poromas, and recent studies have identified specific genetic fusions like PAK1/2/3 in some cases.
- In a study of 12 porocarcinoma patients, most were older males with tumors located on various parts of the body, and some patients developed distant metastases.
- The research indicates that PAK1/2/3 fusions might drive cancer development in porocarcinomas that do not have YAP1 rearrangements, highlighting a potential target for treatment.
