Acne agminata: dermoscopic features and a short review
Acne agminata is a rare idiopathic inflammatory dermatosis. Treatment is variable with no clear consensus. We herein report a case of a 31-year-old man with sudden onset papulonodular eruptions on his face over two months. Histopathological examination revealed superficial granuloma composed of epithelioid histiocytes and scattered multinucleated giant cells, confirming acne agminata. Dermoscopy showed focal orangish structureless areas with follicular openings with white keratotic plugs. He achieved complete clinical resolution with oral prednisolone in 6 weeks. We also reviewed the literature regarding the reported treat...

Cerebriform eruption related to acute coral dermatitis
A 27-year-old woman presented with an acute, tender, geographic lesion on her left shin that developed after contact with a brain coral while scuba diving. Photographs obtained two hours after the incident reveal a well-demarcated, geographic, erythematous plaque with a serpiginous and cerebriform pattern at the site of contact, resembling the outermost surface contour of brain coral. The plaque resolved spontaneously over a three-week period. The biology of corals and potential biological features that lead to cutaneous eruptions are reviewed. (Source: Dermatology Online Journal)

Trichodysplasia spinulosa: a presentation of polyomavirus infection in immunosuppressed patients
Trichodysplasia spinulosa (TS) is a rare skin condition that occurs mainly in immunosuppressed patients. Although initially postulated to be an adverse effect of immunosuppressants, TS-associated polyomavirus (TSPyV) has since been isolated from TS lesions and is now considered to be the causative agent. Trichodysplasia spinulosa presents with folliculocentric papules with protruding keratin spines, most commonly on the central face. Trichodysplasia spinulosa can be diagnosed clinically, but the diagnosis can be confirmed with histopathological examination. Histological findings include the presence of hyperproliferating i...

A crack in the armor: Wolf isotopic response manifesting as cutaneous lupus
We present a patient with systemic lupus erythematosus who developed CLE in a dermatomal distribution following herpes zoster. When CLE lesions present in a dermatomal distribution, these cases may be difficult to distinguish from recurrent herpes zoster infection in an immunosuppressed patient. Therefore, they pose a diagnostic challenge and require balancing antiviral therapy with immunosuppression to sufficiently maintain adequate control of the autoimmune disease while addressing possible infections....

Primary cutaneous CD4+ small/medium-sized pleomorphic T-cell lymphoproliferative disorder in a young woman
Primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder (CD4+PCSM-LPD) is a low-grade cutaneous T cell disorder. There is no standardized approach to treatment of CD4+ PCSM-LPD due to its rarity. Herein, we discuss a 33-year-old woman with CD4+PCSM-LPD which resolved after a partial biopsy. We highlight that conservative and local treatment modalities should be considered prior to utilizing more aggressive and invasive treatment options. (Source: Dermatology Online Journal)

Large, linear pigmentation anomaly: an unusual dyspigmentation case
Segmental pigmentation anomalies can be further divided into segmental pigmentation disorder (SPD) complex and café-au-lait macules (CALMs). Both are congenital skin conditions characterized by hyper- or hypopigmentation. Segmental pigmentation disorder is a rare entity, whereas CALMs are common skin lesions that may be associated with various genetic conditions, especially when several are present and the patient has other indicators of a genetic abnormality. When the CALM is segmental, segmental neurofibromatosis (type V) may be considered in the differential diagnosis. Herein we present a 48-year-old woman with a histo...

Importance of and instruction for starting a vitiligo patient support group
Starting and maintaining a vitiligo support group can appear to be a daunting task. However, with proper planning and organization, the process can become manageable and rewarding. Our guide details the reasons to start a vitiligo support group, how to start a group, how to run a group, and how to promote a group. Legal protections and details regarding retention and funding are also discussed. The authors have extensive experience leading and/or assisting support groups for vitiligo and other disease states and we also sought out other current vitiligo support leaders for their valuable insights. Previous research has fou...

Bleeding complication following a shave biopsy in a patient taking ibrutinib
We report a patient with CLL on ibrutinib who experienced significant and prolonged bleeding after a routine superficial tangential shave biopsy for suspected squamous cell carcinoma. This prompted temporary cessation of this medication for the patient's subsequent Mohs surgery. This case demonstrates the possible severity of bleeding following routine dermatologic procedures. It is important to consider holding the medication prior to planned procedures such as dermatologic surgery. (Source: Dermatology Online Journal)

Characteristics of patients with juvenile dermatomyositis from 2001-2021 at a tertiary care center
Background: Juvenile dermatomyositis (JDM) is the most common inflammatory myopathy in the pediatric population and can represent a medical emergency. However, many features of JDM remain poorly understood, disease presentation is highly variable, and predictors of disease course have yet to be identified.Methods: This retrospective chart review included 47 JDM patients seen at a tertiary care center over a 20-year period. Characteristics such as demographics, clinical signs and symptoms, antibody positivity, dermatopathology features, and treatments were recorded.Results: All patients had evidence of cutaneous involvement...

Linear IgA bullous dermatosis of childhood
A 4-year-old boy presented with blistering on his face and distal upper and lower extremities. Subepidermal blisters containing neutrophils and eosinophils visualized on histology supported the diagnosis of linear IgA bullous dermatosis of childhood (LABDC). The dermatosis presents with vesicles and tense blisters in an annular distribution, erythematous papules, and/or excoriated plaques. Histopathology shows subepidermal blisters with a neutrophilic infiltrate in the dermis, mainly concentrated at the tips of dermal papillae in the early stage of the disease, which can be mistaken for the pattern of neutrophilic infiltra...

Dermatology urgent care model reduces costs and healthcare utilization for psychodermatology patients - a retrospective chart review
Background: Patients with psychiatric dermatoses may be high users of healthcare, especially emergency services. A dermatology urgent care model may reduce healthcare utilization in this population. Objective: To determine whether a dermatology urgent care model can reduce healthcare utilization among patients with psychiatric dermatoses. Methods: We conducted a retrospective chart review of patients seen in dermatology urgent care at Oregon Health and Science University between 2018 and 2020 with diagnoses of Morgellons disease and neurotic excoriations. Rates of diagnosis-related healthcare visits and emergency departmen...
