Article Synopsis
- Cutaneous reactive lymphoid proliferation (CRLP) mimics cutaneous lymphoma, making it essential to differentiate between the two for correct diagnosis and treatment.* -
- CRLP can be caused by factors like viruses, drugs, or skin trauma, and requires careful evaluation of clinical and histopathological features for accurate diagnosis.* -

J Eur Acad Dermatol Venereol
August 2024
Service de Pathologie, Hôpital Saint-Louis, AP-HP, Paris, France.
Article Synopsis
- The classification of primary cutaneous lymphomas and lymphoproliferative disorders is evolving, with two new systems: the 5th edition of the WHO classification and the International Consensus Classification (ICC).

Department of Dermatology and Allergology, Municipal Hospital Dresden, Dresden, Germany.
Article Synopsis
- Borreliosis, or Lyme disease, is caused by the Borrelia burgdorferi bacteria and primarily transmitted by ixodoid ticks, especially affecting children aged five to nine.

Department of Dermatology, School of Medicine, University of Antioquia, Medellín, Colombia.
Article Synopsis
- Tattoos have a long history, but complications can arise from different pigments and application methods; these reactions can be categorized into inflammatory, infectious, neoplastic, aesthetic, and miscellaneous types.
- Histopathological studies of inflammatory reactions show various patterns, such as lichenoid or granulomatous changes.
- A significant number of tattooed individuals (up to 67%) report adverse reactions, with certain pigments, especially red ink, being common culprits; pre-existing skin conditions may worsen with tattoos, highlighting the importance of a dermatological consult before getting inked.
Cutaneous lymphoproliferative disorders: Back to the future.
J Cutan Pathol
June 2024
Department of Dermatology, Leiden University Medical Center, Leiden, The Netherlands.
Article Synopsis
- In the 1980s, immunohistochemistry and clonality analyses advanced the understanding and classification of cutaneous T-cell lymphoma (CTCL) and cutaneous B-cell lymphoma (CBCL), allowing for more accurate diagnoses.
- New criteria based on T-cell antigen loss and clonal gene rearrangements shifted many previously misclassified cases to legitimate lymphoma categories, such as primary cutaneous CD4+ small/medium T-cell lymphoma and primary cutaneous marginal zone lymphoma.
- Recent findings have indicated that low-grade CTCL and CBCL exhibit indolent behavior and high survival rates, prompting revisions in classifications, with some malignancies now identified as lymphoproliferative disorders (LPD) rather than true malignancies.
Features of tattoo-associated cutaneous lymphoid hyperplasia on reflectance confocal microscopy and line-field confocal optical coherence tomography.

Department of Dermatology, ASST Spedali Civili di Brescia, University of Brescia, Brescia, Italy.
Article Synopsis
- The popularity of tattoos has led to more skin reactions, including infections, allergies, and a rare condition called tattoo-induced cutaneous lymphoid hyperplasia (CLH), which mimics skin cancer.
- A study from September 2021 to May 2023 used advanced non-invasive tools like reflectance confocal microscopy (RCM) and line-field confocal optical coherence tomography (LC-OCT) to analyze suspicious tattoo-related lesions in five patients diagnosed with CLH.
- Findings showed that both RCM and LC-OCT effectively identified features of CLH, such as lymphocyte infiltration patterns, and they may offer a cost-effective and efficient alternative to traditional biopsies for diagnosing tattoo-related skin complications in the future.
Stenotrophomonas maltophilia skin infection in an immunocompetent patient: Primary cutaneous CD30+ T-cell lymphoproliferative disorder or pseudolymphoma?
J Cutan Pathol

Dermatopathology Unit, San Gallicano Dermatological Institute IRCCS, Rome, Italy.
Article Synopsis
- Cutaneous pseudolymphomas are a diverse group of skin diseases that look like cutaneous lymphoma but have different causes and symptoms, and they may appear without any known trigger or following factors like medications, tattoos, or infections.
- These conditions can present in various ways, from single lesions to widespread issues, with some cases lasting from weeks to years and potentially recurring after disappearing on their own or after treatment.
- The case study discussed involves a man with a single nodule that was identified as resembling a primary cutaneous CD30+ T-cell lymphoproliferative disorder, highlighting the complex nature of diagnosing these skin diseases.

Article Synopsis
- PC-SMTLD is a skin disorder that often resembles pseudolymphoma, making it difficult to diagnose, typically appearing as nodules or plaques, especially on the head and neck.!* -
- The study found that levels of 5-hydroxymethylcytosine (5-hmC) were significantly lower in PC-SMTLD compared to pseudolymphoma, indicating a potential marker for distinguishing between the two disorders.!* -
- Although the study had a small sample size, the results suggest that low 5-hmC levels in CD4 lymphocytes could indicate a more serious condition like PC-SMTLD, while higher levels could suggest a benign condition like pseudolymphoma.!*
