The authors address the entity of cutaneous lymphadenoma. Although considered benign, cutaneous lymphadenoma can be easily misdiagnosed as basal cell carcinoma because of its close clinical and histological resemblance. This entity is rare and controversial both in terms of its histogenesis and the various diagnostic terms assigned to it throughout the literature. While rare, cutaneous lymphadenoma should be considered in the differential of any facial nodule or papule in addition to the more common basal cell carcinoma, nevi, cysts, and appendiceal tumors...

The authors present a case of Merkel cell carcinoma (MCC) with unique immunohistochemical staining characteristics. A 57-year-old woman presented with a firm 0.3 cm tan papule on her left nasal-labial fold that was reportedly increasing in size and bleeding. She had a history of multiple head and neck actinic keratoses, papillary thyroid carcinoma, and a family history of an uncle with melanoma. The clinical differential diagnosis was "non-melanoma skin cancer." Histological examination showed a markedly atypical-appearing basaloid neoplasm, present mostly in the dermis, with focal pagetoid spread into the epidermis...

A middle-aged Japanese man who had been on haemodialysis treatment for diabetic nephropathy developed multiple itchy papules and nodules, which were histopathologically diagnosed as acquired perforating dermatosis. Two years later he developed oral lesions and subsequently numerous erosive plaques with necrotic crusts on the trunk and extremities. Histopathology of a papule showed a parakeratotic plug intermingled with basophilic, necrotic debris and collagen bundles, along with penetration of collagen bundles across the epidermis and subepidermal blister...

A 17-year-old male patient presented with multiple discrete and confluent monomorphic skin-colored pinhead-sized follicular papules, with occasional pustules distributed on the neck, upper chest, upper posterior trunk, and proximal extremities of 4 months duration. The lesions were asymptomatic, and there was no prior history of topical application or history of atopic dermatitis. Routine investigations were normal. Histopathology of the papules showed a mononuclear infiltrate at the infundibulum of the hair follicle...

Sweet's syndrome (SS) is a rare condition characterized by the abrupt appearance of painful skin lesions due to neutrophilic dermal infiltration. Hematologic neoplasms, particularly acute myeloid leukemia (AML) and myelodysplastic syndromes (MDSs), have been commonly reported in association with SS. Clonal hematopoiesis of indeterminate potential (CHIP) is an emerging entity that is a precursor state to myeloid neoplasms. CHIP has not been previously associated with SS. We report the case of a 71-year-old man who presented with recurrent, painful edematous and erythematous papules and nodules for 18 months despite treatment with corticosteroids...

BACKGROUND: Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by the development of benign hamartomas in multiple organs. Most patients with TSC exhibit cutaneous manifestations. METHODS: We report a 28-year-old patient with multiple pink papules at the proximal nail fold of several toes. RESULTS: Histopathological analysis of a biopsy of a papule was consistent with an ungual fibroma. Histopathological analysis of a biopsy of an elevated skin-colored plaque at the lower back was diagnostic for a Shagreen patch...

Papular epidermal nevus with "skyline" basal cell layer (PENS) is a very rare type of keratinocytic nevus and is associated with extracutaneous findings such as neurological symptoms in about 50% of the cases. Therefore, it is also referred to as PENS syndrome. Clinically visible hyperkeratotic papules and plaques already appear at birth or shortly thereafter, while neurological symptoms such as epilepsy and mental retardation manifest themselves during childhood. Genetics suggests gonadal mosaicism as a possible cause for the disease...

Reported herein is the first case of Leishmania-human immunodeficiency virus (HIV) coinfection in Ecuador. In Ecuador, HIV infections overlap endemic areas of leishmaniasis. Immunosuppression is a well-established risk factor for developing severe disease. This is a severe case of a 32-year-old man presenting with disseminated pleomorphic ulcers, papules, and cutaneous plaque-like lesions over his whole body. Numerous amastigotes were observed in both skin scrapings and biopsies. The sequence of the cytochrome b gene confirmed the presence of Leishmania guyanensis The patient was treated but failed to respond to meglumine antimoniate and amphotericin B...

Dermatomyositis is an idiopathic inflammatory myopathy that cause skin and muscle complications. The ethiology is not understood well yet. Released cytokines including interferon and interleukins are suggested to make inflammatory responses in the skin or muscle. Muscle weakness and skin lesions including heliotrope rash, shawl sign and Gottron's papules are the most common symptoms. A biopsy (muscle or skin) is always the most reliable method for diagnosis. Corticosteroids in association with immunosuppressive agents are used as standard treatment...

BACKGROUND: Immune checkpoint blockade therapy (ICBT) for the treatment of melanoma has led to an important improvement of overall survival in advanced stage patients. However, secondary cutaneous maculopapular eruptions (CMPEs) are frequent and remain poorly characterized. METHODS: We performed a retrospective analysis of melanoma patients from our institution who developed CMPEs during ICBT. Clinical information was retrieved, and histopathological and immunohistochemical characterization was performed by two pathologists...

Hidradenitis suppurativa (HS) is a chronic skin disorder of the terminal follicular epithelium of apocrine sweat glands, manifesting as painful and exudative papules, pustules, cysts or nodules. This inflammatory condition often presents with other systemic and cutaneous disorders. We present the case of an African-American man with HS who was also diagnosed with neutrophilic dermatoses and diverticular disease. Neutrophilic dermatosis was identified based on histopathology findings. Our patient underwent multiple surgeries for flaring of his skin condition...

Orf virus (ORFV) is the type species of the Parapoxvirus genus of the family Poxviridae and infects sheep and goats, often around the mouth, resulting in acute pustular skin lesions. ORFV encodes several secreted immunomodulators including a broad-spectrum chemokine binding protein (CBP). Chemokines are a large family of secreted chemotactic proteins that activate and regulate inflammation induced leukocyte recruitment to sites of infection. In this study we investigated the role of CBP in vivo in the context of ORFV infection of sheep...

Atopic dermatitis (AD) commonly identified as eczema. AD is an inflammatory, long-lasting, highly pruritic reverting disease of the skin. AD is classified by disease of outer skin layer barrier function. AD is progress with Immunoglobulin E facilitated sensitization to food and environmental allergens. One study stated that more than 59.6% of teen-agers with AD are at high risk of develop asthma or rhinitis. Interaction between genes and environment increase the prevalence of AD. AD have three standard stages: infantile, childhood, and adulthood...

: 227 Background: Knowledge of immune-system regulation led to the discovery of immune checkpoints molecules, which have demonstrated anti-tumor activity across various malignancies. These advances represent a new set of challenges for clinicians, including non-oncologists treating the cancer patient, who must develop a working knowledge of the mode of action of these agents, their unique response kinetics, and how to diagnose and effectively manage their toxicities. Nivolumab is a monoclonal immune checkpoint antibody that binds to the PD-1 receptor on T-cells, blocking PD-1 pathway-mediated anti-tumor immune response inhibition...

REVIEW
Mauro Picardo, Lawrence F Eichenfield, Jerry Tan
Acne, one of the most common skin diseases, affects approximately 85% of the adolescent population, and occurs most prominently at skin sites with a high density of sebaceous glands such as the face, back, and chest. Although often considered a disease of teenagers, acne is occurring at an increasingly early age. Rosacea is a chronic facial inflammatory dermatosis characterized by flushing (or transient facial erythema), persistent central facial erythema, inflammatory papules/pustules, and telangiectasia. Both acne and rosacea have a multifactorial pathology that is incompletely understood...
