Background: Folliculotropic mycosis fungoides (FMF) is a variant of cutaneous T-cell lymphoma that has clinical overlap with a variety of inflammatory follicular unit disorders. However, we describe distinctive presentations of FMF with acneiform features that can be diagnostically challenging, leading to diagnostic delay.

Objective: To highlight the importance of histopathologic and immunohistochemical evaluation for diagnostic confirmation of presumed inflammatory follicular unit-based disorders that are unusual in presentation or unresponsive to standard therapies.

INTRODUCTION No research has been found regarding outcomes of dermoscope-guided surgical procedures in primary care. AIM To establish whether outcomes of dermoscope-guided procedures performed in primary care settings differ from outcomes for similar procedures, performed without the use of a dermoscope. METHODS A retrospective case-control study design was used.

Cutaneous reactions to red tattoo pigment rarely manifest as pseudolymphomatous reactions. We describe an exceedingly rare case of red tattoo-related T-cell predominant pseudolymphoma microscopically mimicking mycosis fungoides. Careful clinicopathological correlation was required to obtain the correct diagnosis and aid in an effective treatment course.

A 46-year-old woman with a 30 pack-year smoking history presented with a worsening eruption on the left cheek that failed to improve with metronidazole gel. The cutaneous eruption spread to most of her face and did not respond to a brief tapering course of prednisone. During the initial evaluation at our institution, approximately 6 weeks after the onset of the cutaneous eruption, the patient had erythematous, crusted plaques on her face and scalp (Figure 1A); they were also present on the V-area of the anterior aspect of the neck and upper region of the chest, the shoulders, and the arms, with isolated lesions on the trunk and legs.

Multiprotein complexes transduce cellular signals through extensive interaction networks, but the ability to analyze these networks in cells from small clinical biopsies is limited. To address this, we applied an adaptable multiplex matrix system to physiologically relevant signaling protein complexes isolated from a cell line or from human patient samples. Focusing on the proximal T cell receptor (TCR) signalosome, we assessed 210 pairs of PiSCES (proteins in shared complexes detected by exposed surface epitopes).

Objectives: To investigate whether Gianotti-Crosti syndrome (GCS) in children is associated with atopy.

Methods: The setting was two outpatient clinic. Diagnoses of asthma and atopic dermatitis (AD) were made according to internationally accepted diagnostic criteria.

Article Synopsis
  • The text discusses various skin rashes linked to viral infections, highlighting notable syndromes like pityriasis rosea (PR), Gianotti-Crosti syndrome (GCS), and others, including a newly identified rash called eruptive hypomelanosis (EH).
  • A systematic review of studies over the last 60 years was conducted to analyze epidemiological data and assess whether these rashes are caused by infectious agents, leading to the selection of numerous relevant articles.
  • The findings suggest moderate support for PR, GCS, and asymmetric periflexural exanthem (APE) being linked to infectious causes, while the evidence for the other conditions, including EH, is considered inadequate, indicating potential for future research.

Background: Published case series describe lenalidomide as an effective treatment of refractory cutaneous lupus erythematosus (CLE).

Objectives: The present study aimed to further characterize lenalidomide use in the treatment of CLE.

Methods: A retrospective review of patients treated with lenalidomide for CLE from January 1, 2000, to December 17, 2014, was conducted.

We report two cases of doxycycline-induced solar urticaria that developed shortly after initiation of therapy with persistence despite discontinuation. Consequently, dermatologists should be aware of the association between doxycycline and solar urticaria and counsel their patients on the potential for this side effect when prescribing doxycycline.

Human herpesviruses (HHVs) have frequently been suspected as etiologic agents or cofactors in cutaneous disease. However, clearly established associations are rare. Investigations into an etiologic association between HHVs and cutaneous disease are complicated by the ubiquity and nearly universal prevalence of some herpesviruses.

Several exanthems including Gianotti-Crosti syndrome, pityriasis rosea, asymmetrical periflexural exanthem, eruptive pseudoangiomatosis, and papular-purpuric gloves and socks syndrome are suspected to be caused by viruses. These viruses are potentially dangerous. Gianotti-Crosti syndrome is related to hepatitis B virus infection which is the commonest cause of hepatocellular carcinoma, and Epstein-Barr virus infection which is related to nasopharyngeal carcinoma.

Article Synopsis
  • - Becker nevus is a type of skin condition that can sometimes be linked to other medical issues, known as Becker nevus syndrome, and this study highlights a specific case where it was associated with a desmoid soft-tissue tumor.
  • - The research reviewed 52 cases of Becker nevi at the Mayo Clinic, revealing that 12 of these patients had various associated abnormalities, including conditions affecting bones and soft tissues.
  • - This case aims to increase awareness among healthcare providers that Becker nevus can signify deeper issues requiring thorough investigation, emphasizing the need for careful follow-up and examination of underlying tissues.

Background: Osteosarcoma is a common malignancy, although skin metastasis is rare. We sought to review the incidence, epidemiology, risk factors, and prognosis of osteosarcoma with skin involvement.

Methods: We conducted a retrospective chart review that covered 30 years and involved clinic patients younger than 18 years who had cutaneous metastases of osteosarcoma.

Idiopathic proctodynia, an enigmatic pain syndrome affecting the perianal region, can be persistent, relatively refractory to treatment, and associated with considerable psychological distress. The authors present the case of a patient with a long history of severe proctodynia that had been resistant to a range of topical and systemic treatments. With the use of topical amitriptyline hydrochloride 2.

Atopic dermatitis (AD) is a common pruritic dermatitis with macroscopically non-lesional skin that is often abnormal. Therefore, we used high-density oligonucleotide arrays to identify cutaneous gene transcription changes associated with early AD inflammation as potential disease control targets. Skin biopsy specimens analysed included normal skin from five healthy non-atopic adults and both minimally lesional skin and nearby or contralateral non-lesional skin from six adult AD patients.

Objective: To detect temporal case clustering in patients with pityriasis rosea in different geographic locations.

Design: Regression analysis of dates on which 1379 patients were diagnosed as having pityriasis rosea in 3 different geographic locations. The control data consisted of dates of diagnosis of patients with psoriasis in the same settings.
