BACKGROUND: Indoor mold levels typically increase after natural disasters, flooding, and water damage. Eurotium herbariorum is the sexual stage of Aspergillus glaucus. Case Presentation A 66-year-old, Japanese male, ex-smoker had been diagnosed with bronchial asthma when he was five years old; he achieved remission at the age of 13 years. He was displaced from his home during the Great East Japan Earthquake on March 11, 2011 and moved to temporary housing in Miyagi Prefecture in June 2011...

CD30-positive primary cutaneous T-cell lymphoma (CTCL) includes mycosis fungoides, anaplastic large-cell lymphoma and lymphomatoid papulosis type A. Brentuximab vedotin (BV) consists of an antibody targeting CD30 with a protease-cleavable linker to vedotin. CD30 binding allows internalization of BV inducing cell-cycle arrest and apoptosis. Response rates >75% with manageable adverse effects in refractory Hodgkin lymphoma and systemic anaplastic large-cell lymphoma led to accelerated approval for both. Phase II studies in CD30-expressing CTCL followed and showed similar efficacy, which was ratified in a Phase III trial of BV versus physician's choice (methotrexate or bexarotene) showing significant improved responses without increase in severe adverse effects although peripheral neuropathy is frequent...

Hypopigmented mycosis fungoides (HMF) is the most common variant of mycosis fungoides (MF) in children. Large-cell transformation in HMF has never been reported. Herein we report a case of HMF in an 8-year-old boy who presented with a 6-year history of hypopigmented patches on the bilateral arms, lower back, buttocks, posterior thighs, and lower legs. Biopsy revealed an abnormal CD8(+) epidermotropic T-cell infiltrate consistent with the diagnosis of MF. The T-cell clonality study was positive. The patient was started on narrowband ultraviolet B (NBUVB) phototherapy and topical steroids...

INTRODUCTION: Population-level survival has improved for common haematologic malignancies in the early 21st century. However, relatively few population-level data are available for rare haematologic malignancies. METHODS: Data were extracted from 12 cancer registries in Germany and the Surveillance, Epidemiology and End Results database in the United States (US). Cases of haematologic malignancies with an incidence of less than 1 per 100,000 were selected for analysis...

The aim of the present study was to assess the effectiveness of UVA1 and PUVA therapy in treating patients with mycosis fungoides (MF) and to evaluate high-frequency ultrasonography (HF-USG) to monitor the clinical response of these patients. A total of 18 patients diagnosed with MF (stages I-IIA) underwent phototherapy, either UVA1 (6 cases) or PUVA (12 cases). Clinical response was evaluated according to modified Severity Weighted Assessment Tool (mSWAT) criteria and HF-USG (20 MHz). In the PUVA group, 50% of patients (6/12) achieved complete remission (CR) versus 33% (2/6) of patients in the UVA1 group...

Histoplasmosis is the most common endemic mycosis in the United States. Symptomatic gastrointestinal histoplasmosis is a rare entity. We report a case of isolated intestinal histoplasmosis that manifested as severe lower gastrointestinal bleeding in a renal transplant patient. The patient developed hematochezia, and colonoscopy showed diffuse, extensive areas of cratered, ulcerated mucosa in the entire colon. Biopsy showed prominent mucosal and submucosal infiltrate of plump histiocytes containing intracytoplasmic yeast forms morphologically compatible with florid histoplasmosis...

BACKGROUND: Digital pathology offers numerous advantages, allowing remote information sharing using whole slide imaging (WSI) to digitize an entire glass slide at high resolution, creating a digital slide. METHODS: In this study, we examine the concordance in diagnoses made on 40 digital slides (DS) versus traditional glass slides (GS) in differentiating between spongiotic dermatitis (SD) and patch/plaque-stage mycosis fungoides (MF). RESULTS: Greater interobserver concordance rate in final diagnosis of SD vs MF was observed with the utilization of DS (86...

BACKGROUND: Phototherapy has been a mainstay in the treatment of mycosis fungoides (MF). However, the recent findings of UV-induced p53 mutations in advanced MF suggest that phototherapy may contribute to disease progression. OBJECTIVE: The objective of this study was to evaluate the effect of phototherapy on the time to tumor progression and overall survival in MF. MATERIALS AND METHODS: Retrospective analysis of patients seen at the University of Pittsburgh Cutaneous Lymphoma Clinic from 1979 to 2016...

Fungi often infect mammalian hosts via the respiratory route, but traumatic transcutaneous implantation is also an important source of infections. Environmental exposure to spores of pathogenic fungi can result in subclinical and unrecognised syndromes, allergic manifestations, and even overt disease. After traumatic cutaneous inoculation, several fungi can cause neglected mycoses such as sporotrichosis, chromoblastomycosis, mycetoma, entomophthoramycosis, and lacaziosis. Most of these diseases have a subacute to chronic course and they can become recalcitrant to therapy and lead to physical disabilities, including inability to work, physical deformities, and amputations...

REVIEW
J P Nicolay, C Assaf
Adequate therapeutic management of cutaneous T-cell lymphoma (CTCL) requires the identification of the exact CTCL stage and entity within the current WHO classification. There is no curative therapy for CTCL yet, so that treatment currently aims at improving symptoms and quality of life as well as reducing relapse rates. The treatment has to be stage-adapted. Therapeutic options comprise skin-directed as well as systemic treatment. In early stages, phototherapy and local steroids are the first-line therapeutic options...

BACKGROUND: The utility of brentuximab vedotin (BV) in CD30(+) systemic lymphomas is established, however evidence for treating primary cutaneous lymphoma remains limited. This study aimed to evaluate BV in treating CD30(+) transformed mycosis fungoides (MF) and primary cutaneous anaplastic large cell lymphoma (PC-ALCL). METHODS: A literature review was conducted, and we analyzed data from published trials and case reports obtained via search of Ovid-MEDLINE(®) and PubMed databases...

David R Pearson, Mayumi Fujita, Whitney A High
We describe two unique cases of fulminant mycosis fungoides with remarkably similar and aggressive clinical courses resulting in death. Both cases demonstrated ulcerated palmar and periorbital plaques and marked tissue eosinophilia, which was confirmed by T-cell receptor γ chain gene rearrangement studies to display identical monoclonality at temporally and anatomically distinct sites. Dense eosinophilic infiltrates on biopsy led to misdiagnosis of inflammatory dermatoses in both instances. While mycosis fungoides may be challenging to diagnose histologically, the presence of eosinophils in progressive disease may herald a poor prognosis and should not exclude the diagnosis...

Metarhizium (M.) granulomatis (formerly Chamaeleomyces granulomatis) invariably causes fatal fungal glossitis and systemic mycosis in veiled chameleons (Chamaeleo calyptratus). Isolation of M. granulomatis in other lizards thus far has not been described. The aim of this study therefore was to obtain information on the presence of M. granulomatis in reptiles kept as pets, and to examine whether there was an association between specific genotypes and clinical/pathological outcomes. Besides 18S ribosomal (r) DNA (SSU) and internal transcribed spacer1-5...

Organ transplant recipients receiving immunosuppression have an increased risk of developing post-transplant lymphoproliferative diseases (PTLDs). Traditionally, PTLDs refer to Epstein-Barr virus (EBV)-induced B-cell lymphoma. However, post-transplant T-cell lymphoma may also occur and tends to have a poorer response to reduced immunosuppressive therapy. As such, additional therapy is often needed for post-transplant T-cell lymphoma, including post-transplant cutaneous T-cell lymphoma (PT-CTCL). We present only the third case of PT-CTCL occurring after liver transplantation...

Mycosis fungoides (MF) accounts for approximately 50% of all primary cutaneous lymphomas. MF occurrence in the oral cavity is extremely rare with approximately 45 cases reported to date. We present a case of a 68 year-old man with a raised nodular lesion of the ventral tongue with clinical impression of irritational fibroma. Histopathologic and immunohistochemical (IHC) examination revealed a phenotype consistent with MF with large cell transformation in the context of Sezary syndrome. The histological diagnosis of oral MF requires a high index of suspicion and IHC panel to rule out large cell transformation...

Among the endemic deep mycoses in Latin America, paracoccidioidomycosis (PCM), caused by thermodimorphic fungi of the Paracoccidioides genus, is a major cause of morbidity. Disease development and its manifestations are associated with both host and fungal factors. Concerning the latter, several recent studies have employed the methodology of gene modulation in P. brasiliensis using antisense RNA (AsRNA) and Agrobacterium tumefaciens-mediated transformation (ATMT) to identify proteins that influence fungus virulence...

Talaromyces marneffei is a dimorphic fungus endemic mainly in southeast and south Asia. It causes severe mycosis, usually in immunocompromised individuals, such as those with human immunodeficiency virus (HIV) infection. Concomitant infection with T. marneffei and other opportunistic pathogens is plausible because the majority of T. marneffei infections occur in patients with advanced HIV infection. Nonetheless, coinfection in the same site has rarely been reported, and poses a considerable diagnostic and therapeutic challenge...
