Causes of Death in Cutaneous T-Cell Lymphoma Patients.

Background: The advancing evolution toward a Th2 immune environment confers a progressive immunosuppression in patients with longstanding cutaneous T-cell lymphoma (CTCL). The conjunction of the disease-related immunosuppression as well as the immunosuppressive character of some CTCL treatments increase the risk of infectious and neoplastic diseases, sometimes with fatal outcomes.

Objectives: The aim of the study was to prospectively study the causes of death in a cohort of CTCL patients, in a tertiary university skin cancer center.

Cemiplimab for locally advanced and metastatic basal cell carcinoma.

Introduction: Locally advanced basal cell carcinoma (laBCC) represents approximatively 1% of all BCCs. Metastatic BCC (mBCC) is even more rare. Most cases are observed in immunocompromised patients, particularly solid organ transplant recipients (OTRs).

A Comprehensive Update of the Atypical, Rare and Mimicking Presentations of Mycosis Fungoides.

Introduction: Mycosis fungoides (MF) is the most frequent subtype of primary cutaneous T cell lymphomas (pCTCL). The diagnosis may be particularly difficult in the early stages as well as in atypical and rare clinical presentations. Furthermore, MF may simulate a large variety of common dermatologic disorders and patterns, both histopathologically and clinically.

Cemiplimab for locally advanced cutaneous squamous cell carcinoma: safety, efficacy, and position in therapy panel.

Introduction: Locally advanced cutaneous squamous cell carcinoma (lacSCC) is rare. Approximately one-fourth of the cases are observed among immunocompromised patients, in particular in solid organ transplant recipients (OTRs). LacSCC has a very poor prognosis.

Cutaneous Breast Cancer Metastases Successfully Treated Using an Oxygen Flow Assisted Topical Administration of Methotrexate (OFAMTX).

Introduction: Cutaneous metastases of breast cancer remain a therapeutic challenge. Oxygen flow-assisted topical administration of methotrexate 5% (OFAMTX, 5% methotrexate in a carrier solution) has recently been proven to be an efficacious alternative treatment for extramammary Paget's disease, which is considered to be an in situ mammary adenocarcinoma of the epidermis.

Case Report: A 51-year-old patient with triple negative breast cancer presenting with biopsy-proven skin metastases on the chest agreed to a treatment with OFAMTX5%.

Exploratory Assessment of Oxygen Flow-Assisted Cutaneous Administration of Methotrexate for Superficial Basal Cell Carcinoma, Mycosis Fungoides, and Extramammary Paget Disease.

The molecular weight of methotrexate (MTX) makes cutaneous penetration difficult. Oxygen flow could enhance the skin permeation of MTX diluted in the proprietary LP3 carrier system. This pilot study aims to assess the efficacy, safety, and tolerance of oxygen flow-assisted LP3-MTX3% for treating superficial skin cancers.

Granulomatous Reactions from Tattoos Following BRAF Inhibitor Therapy.

BRAF inhibitors may present several cutaneous adverse effects, including actinic keratosis, squamous cell carcinoma, keratoacanthoma, rashes, increased photosensitivity, panniculitis, palmoplantar and capillary involvement, pruritus and xerosis as well as granulomatous reactions. A 30-year-old patient with multiple tattoos received dabrafenib and trametinib for metastatic melanoma. After 4 months, he developed an induration and thickening strictly limited to several tattoos.

Giant morphea-form basal cell carcinoma of the umbilicus: Successful debulking with vismodegib.

Basal cell carcinoma of the umbilicus is very rare. The nodular subtype is the main representative. Giant basal cell carcinomas represent around 1% of all basal cell carcinomas.

Pachyderma in Primary Cutaneous NK and T-Cell Lymphoma and Leukemia Cutis.

Background: Pachyderma is defined as severely thickened skin with deep folds and is occasionally observed with primary cutaneous NK and T-cell lymphoma (pCNKTCL), primary cutaneous B-cell lymphoma (pCBCL), and leukemia cutis (LC).

Aim: To describe the clinical, histological, and therapeutic particularities of a series of pCNKTCL, pCBCL, and LC patients with pachyderma.

Results: In a series of pCNKTCL ( = 70), pCBCL ( = 12), and LC ( = 2) patients followed up during 9 years, 6 cases of pachyderma were observed.

Eruptive Seborrheic Keratoses Restricted to Plaque/Patch-Stage Mycosis Fungoides.

Eruptive seborrheic keratoses (ESK) are rare in dermatology. They are usually inflammatory in nature and may be encountered as Leser-Trélat sign. ESK may also be simultaneously observed with hepatic angiomas, chemotherapy, segmental neurofibromatosis, HIV or erythrodermic pityriasis rubra pilaris, psoriasis, and drug eruption.

Risk Factors for Skin Infections in Mycosis Fungoides.

Background: Mycosis fungoides (MF) is the most frequent type of primary cutaneous natural killer and T-cell lymphoma. MF-required immunosuppressive therapies and MF-related immunosuppressive characteristics render patients with MF more prone to infections.

Aim: To describe the clinical features of cutaneous infections observed in MF patients.

Koebner Phenomenon and Mycosis Fungoides.

Mycosis fungoides (MF) is the most frequent type of primary cutaneous T-cell/NK-cell lymphoma. The Koebner phenomenon is defined as the appearance of cutaneous lesions on previously noninvolved skin following trauma and is observed in a series of cutaneous diseases including psoriasis, lichen planus, viral warts, molluscum contagiosum, etc. In this case report, 3 patients with longstanding MF are presented, the 1st with the appearance of a circumscribed early-stage type MF lesion rapidly following a surgical excision of an infundibular cyst, the 2nd with the appearance of a unique unilateral palmar tumoral MF lesion at the pressure site of a crutch, and the 3rd presented localized MF early stage lesions at the friction site of a belt.
