Dermatological Implications of Galectin-3 in Circulation: An Evaluation From the Perspective of Patients With Differential Manifestations of Post-Kala-Azar Dermal Leishmaniasis.

Am J Dermatopathol 2019 Apr 10. Epub 2019 Apr 10.

Departments of Laboratory Medicine, and.

Galectin-3, a β-galactoside-binding lectin, has been implicated in vast repertoire of inflammatory and immunomodulatory processes including skin diseases. However, galectin-3 has not been comprehensively studied in infectious diseases. This study emphasizes on fascinating aspects of galectin-3 expression in dermal infection by studying post-kala-azar dermal leishmaniasis (PKDL), an intracellular infection caused by Leishmania donovani.

The Conundrum of Diagnosing Cutaneous Composite Lymphoma in the Molecular Age.

Am J Dermatopathol 2019 Apr 2. Epub 2019 Apr 2.

Department of Pathology, Loyola University Chicago, Maywood, IL.

Introduction: Cutaneous composite lymphoma (CCL) is extremely rare. When 2 potentially distinct lymphoid lesions occur at one skin site, distinguishing between one neoplastic clone and a secondary reactionary lymphoid response versus a second neoplasm is difficult. In this study, we describe a unique case of CCL along with a review of reported cases in literature to identify clues and discuss issues that are relevant to the diagnosis of CCL. Read More

Acrochordon With Histological Features of Lichen Sclerosus.

Am J Dermatopathol 2019 Mar 26. Epub 2019 Mar 26.

Section of Dermatology, Department of Medicine, University of Chicago, Chicago, IL.

Lichen sclerosus (LS) is a chronic inflammatory dermatosis that classically presents as sclerotic, atrophic plaques in the genital region. We present a case of acrochordon with histological features of LS, clinically mimicking intradermal nevus, in a 53-year-old man with no prior history of LS. Our case highlights an unusual morphologic variant of acrochordon and illustrates the role of chronic pressure and occlusion in the development of secondary features of LS. Read More

Mycosis Fungoides Associated With Lesions in the Spectrum of Primary Cutaneous CD30+ Lymphoproliferative Disorders: The Same Process or 3 Coexisting Lymphomas?

Am J Dermatopathol 2019 Mar 29. Epub 2019 Mar 29.

Departments of Dermatology.

Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma, primary cutaneous CD30 lymphoproliferative disorders (pc CD30 LPD) being the second most prevalent. There is evidence that MF and pc CD30 LPD may coexist and share T-cell clonality, suggesting a common origin. These findings were supported by a T-cell receptor clonality assessment by the polymerase chain reaction coupled with capillary electrophoresis, although results produced by this method may be ambiguous.

Immunohistochemical Study of 2 Cases of Coxsackie A6-Induced Atypical Hand-Foot-and-Mouth Disease.

Am J Dermatopathol 2019 Mar 20. Epub 2019 Mar 20.

Department of Dermatology, Fundación de Investigación Biomédica del Hospital Universitario de La Princesa, Madrid, Spain.

An atypical clinical variant of hand-foot-and-mouth disease (HFMD) with more extensive lesions and affecting adults has emerged during the past years, usually associated to the Coxsackievirus serotype A6 (CV-A6). We present a 19-year-old woman with a 3-day evolution eruption of papulovesicular lesions, which first appeared around the mouth and frontal area and rapidly spread. In addition, we present a 61-year-old man with a 4-day evolution asymptomatic eruption of papulovesicular lesions in both the hands and feet after suffering a cold 1 week before. Read More

Syringotropic Mycosis Fungoides: A Variant of Folliculotropic Mycosis Fungoides or a Distinct Entity?

Am J Dermatopathol 2019 Mar 20. Epub 2019 Mar 20.

Medical University of South Carolina, Charleston, SC.

Syringotropic mycosis fungoides (MF) is classified under folliculotropic MF. Although there is significant overlap between the 2, this study demonstrates that folliculotropism is frequently present in syringotropic MF, and when not present, the specimen did not include a follicle to examine. In addition, few of the pathology reports mentioned folliculotropism or syringotropism, although this is an important prognostic feature. Read More

Spindle Cell Predominant Trichodiscoma or Spindle Cell Lipoma With Adnexal Induction? A Study of 25 Cases, Revealing a Subset of Cases With RB1 Heterozygous Deletion in the Spindle Cell Stroma.

Am J Dermatopathol 2019 Mar 11. Epub 2019 Mar 11.

Department of Pathology, Faculty of Medicine in Plzen, Charles University, Plzen, Czech Republic.

In our routine and consultative pathology practices, we have noticed that a relatively high proportion of spindle cell predominant trichodiscomas demonstrate a remarkable stromal admixture of adipose tissue, which along with spindle cells, prominent collagen bundles and myxoid change closely resembles spindle cell lipoma (SCL). To clarify their possible relationship to SCL, 25 cases of trichodiscoma and fibrofolliculoma with stromal "lipomatous metaplasia" were collected and examined using immunohistochemical stains [CD34 and retinoblastoma-1 (RB1) protein] and fluorescence in situ hybridization (RB1 deletion). The patients ranged in age from 35 to 81 years (median 64 years). Read More

Subcutaneous Panniculitis-Like T-Cell Lymphoma With Granulomas as the Predominant Feature.

Am J Dermatopathol 2019 Mar 15. Epub 2019 Mar 15.

Department of Dermatopathology, California Skin Institute, San Jose, CA.

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare primary cutaneous lymphoma preferentially localized in the subcutaneous adipose tissue and composed of cytotoxic T cells with an α/β immunophenotype. The neoplastic T cells can be variably admixed with other inflammatory cells, including histiocytes, which can rarely form noncaseating granulomas. We present a case of SPTCL in which granulomas are the predominant feature, composing 75%-80% of the inflammatory infiltrate. Read More

Hyalinized Neurofibromas: Not Just Rare Variants in Skin of the Female Breast.

Am J Dermatopathol 2019 Mar 7. Epub 2019 Mar 7.

Department of Laboratory Medicine, Cleveland Clinic, Cleveland, OH.

Although classical neurofibromas are commonly encountered skin lesions, histologic variants are infrequent. We report a greater than 15-year retrospective review of a single institution's experience with the histopathologic diagnosis of neurofibroma of the female breast with a focus on the hyalinized variant. An electronic histopathology record review (CoPathPlus; Cerner Corp, North Kansas City, MO) was conducted from January 1, 2000, to October 16, 2015, for all "neurofibroma" diagnoses rendered in "females" at the anatomical site "breast".

Differential Expression of PLAG1 in Apocrine and Eccrine Cutaneous Mixed Tumors: Evidence for Distinct Molecular Pathogenesis.

Am J Dermatopathol 2019 Feb 28. Epub 2019 Feb 28.

Department of Pathology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA.

Cutaneous mixed tumors, also known as chondroid syringomas, are benign adnexal neoplasms that share histomorphologic features with pleomorphic adenomas of the salivary gland. Recent work suggests that the similarity between these 2 tumor types extends to the molecular level because both harbor identical chromosomal rearrangements involving the PLAG1 gene. The resulting nuclear PLAG1 overexpression can be detected by immunohistochemistry and has become a useful diagnostic adjunct for both tumor types. Read More

Necrotizing Granulomas in a Patient With Psoriasis and Sarcoidosis After Adalimumab-Medication-Induced Reaction or Reactivation of Latent Disease?

Am J Dermatopathol 2019 Feb 28. Epub 2019 Feb 28.

Dermatopathology Section, Department of Pathology and Laboratory Medicine, VA Boston Healthcare System, MA.

In this report, we describe a case of a patient with a clinical history of systemic sarcoidosis and psoriasis who developed biopsy-confirmed perforating and necrotizing cutaneous granulomas after 12 months of treatment with adalimumab, a tumor necrosis factor-alpha-inhibiting, anti-inflammatory, biologic medication, prescribed for the patient's psoriasis. Although rare reports of a "sarcoidosis-like" reaction associated with select tumor necrosis factor-alpha agents exist, to the best of our knowledge, perforating and necrotizing cutaneous granulomas after treatment with adalimumab has not been previously reported. Given the patient's history of systemic sarcoidosis, the differential diagnosis includes reactivation of latent sarcoidosis with adalimumab as a trigger. Read More

Galectin-1 and Galectin-3 and Their Potential Binding Partners in the Dermal Thickening of Keloid Tissues.

Am J Dermatopathol 2019 Mar;41(3):193-204

Autonomous Service Institute of Biomedicine, Caracas, Venezuela.

Keloids are defined histopathologically as an inflammatory disorder characterized by exhibiting numerous fibroblasts, abnormal vascularization, increased number of proinflammatory immune cells as well as uncontrolled cell proliferation, and exacerbated and disorganized deposition of extracellular matrix (ECM) molecules. Importantly, many of these ECM molecules display N- and O-linked glycan residues and are considered as potential targets for galectin-1 (Gal-1) and galectin-3 (Gal-3). Nevertheless, the presence and localization of Gal-1 and Gal-3 as well as the interactions with some of their binding partners in keloid tissues have not been considered. Read More

Melanoma With Loss of BAP1 Expression in Patients With No Family History of BAP1-Associated Cancer Susceptibility Syndrome: A Case Series.

Am J Dermatopathol 2019 Mar;41(3):167-179

Associate Professor, Dermatopathology Section, Departments of Pathology and Dermatology, The University of Texas MD Anderson Cancer Center, Houston, TX.

The presence of multiple BAP1-negative melanocytic neoplasms is a hallmark of familial cancer susceptibility syndrome caused by germline mutations in BAP1. Melanocytic tumors lacking BAP1 expression may also present as sporadic lesions in patients lacking a germline BAP1 mutation. Here, we report histomorphologic and clinical characteristics of cutaneous melanomas with loss of BAP1 expression in 4 patients with no known history of BAP1-associated cancer susceptibility syndrome.
