An Unusual Case of Chronic Delimited Rhinosinusal Mucormycosis With Secondary Cutaneous Involvement in a Patient With Ataxia-Telangiectasia Syndrome.

Mucormycosis is an immunosuppression-related fungal infection. This pathogen usually manifests as an acute and rapidly progressive, deforming, and lethal disease, but chronic forms of zygomycosis occur rarely. Here we present a case of a 15-year-old female with ataxia-telangiectasia syndrome, reporting a six-month history of recurrent sinusitis and an atypical secondary skin infection characterized by ulcerated nodules and crusted plaques, unresponsive to multiple treatments.

Familial Disseminated Comedones Without Dyskeratosis: A Case Report.

Disseminated familial comedones without dyskeratosis (DFCWD) is a rare autosomal dominant genodermatosis characterized by widespread comedonal eruptions, predominantly affecting the trunk and face, in the absence of histopathological features such as dyskeratosis or acantholysis. While it exhibits clinical overlap with other entities within the spectrum of familial comedonal disorders, its unique histological features and inheritance pattern support its classification as a distinct clinical entity. Due to the limited number of reported cases, its phenotypic spectrum, natural history, and underlying molecular mechanisms remain poorly understood.

Spongiform Venous Malformation Presenting as an Extensive Lesion in the Gluteal Region.

Venous malformations (VMs) are vascular malformations affecting a small portion of the population. A 53-year-old woman presented with a congenital VM on the left gluteal region confirmed through clinical imaging and histopathology. Treatment with sclerotherapy led to significant improvement.

Primary Extramammary Paget's Disease in a Male Patient Exhibiting Genital Involvement Mimicking Clinical and Histopathological Features of Bowen's Disease: A Case Report.

Extramammary Paget's disease (EMPD) is a rare cutaneous neoplasm characterized by the proliferation of malignant glandular-origin cells within the epidermis, occurring in areas other than the mammary areola. It is more prevalent in women (65%) than men (14%). Diagnosis can be confused with other neoplastic, inflammatory, or infectious conditions, often leading to initial inappropriate treatment with antifungals or topical steroids.

Pyoderma Gangrenosum Post Reduction Mammoplasty: An Unusual Postoperative Complication.

We present a case of a patient with pyoderma gangrenosum, a rare complication associated with surgical procedures. Breast reduction is the second most common etiology within this category. This case emphasizes the importance of early diagnosis to start therapy on time to stop the inflammatory process and prevent its progression, achieving adequate re-epithelialization, as well as emphasizes the use of an immunomodulator with steroid treatment to offer better results that impact the quality of life positively.

Idiopathic Atrophoderma of Pasini and Pierini: Response to Mycophenolic Acid Treatment.

Atrophoderma of Pasini and Pierini (APP) is a rare skin condition of unknown etiology. It is characterized by dermal atrophy with single or multiple hyperpigmented, non-indurated, and slightly depressed plaques on the trunk or limbs; unlike morphea, this condition does not cause induration. In this report, we analyze the case of a patient diagnosed with APP with a 19-year history of progression, aiming to highlight the few cases published in the literature.

[The annual cost of medical care for patients with moderate to severe atopic dermatitis in Mexico. A multicenter study].

Background: In Mexico, the economic burden of medical care for patients with atopic dermatitis is unknown.

Objective: To determine the annual direct medical costs of the treatment for patients with moderate to severe atopic dermatitis who receive medical attention at "Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado" (Institute for Social Security and Social Services for State Workers, better known as ISSSTE), as well as the main variables associated with it.

Methods: A multicenter, retrospective cohort study.
