An Atypical Presentation of Molluscum Contagiosum in a Newborn.

Molluscum contagiosum (MC) is a skin infection caused by a poxvirus that is highly contagious and common among children. When MC does occur in children less than one year old, it is suspected to be a result of vertical transmission through maternal MC infection. In this report, we describe a case of MC on the scalp of a 10-month-old child that started shortly after birth via Cesarean delivery.

Neonatal Dermatopathology: A 10-Year Institutional Review.

Background/objective: Neonatal skin conditions are typically diagnosed through noninvasive methods. Few studies describe the spectrum of biopsy- evaluated neonatal skin lesions. We present our institutional experience with the conditions leading to skin biopsies in neonates.

Atrichia With Papular Lesions Confirmed via Genetic Testing: A Case Report.

Atrichia with papular lesions (APL) is a rare form of alopecia characterized by the diffuse, complete, irreversible loss of hair shortly after birth and the presence of diffuse keratotic papules and milia-like cysts. Multiple hairless gene () mutations on the zinc finger domain of chromosome 8p12 have been associated with this disorder. We present the case of a 5-year-old girl with classic clinical findings of APL, with a diagnosis confirmed via genetic testing.

Presentation of cryopyrin-associated periodic fever syndrome as chronic, afebrile urticaria in a 12-month-old female.

A healthy 12-month-old female presented with relapsing and remitting urticaria since birth that was resistant to treatment with antihistamines. A thorough history revealed extensive rheumatic disease on the father's side of the family, and subsequent genetic testing was positive for a missense variant of NLRP3, indicating cryopyrin-associated periodic fever syndrome (CAPS). CAPS encompasses a spectrum of diseases, all related to a defect in the same gene; manifestations vary in severity and presentation, but most are associated with recurrent rash and fever.

A solitary angiokeratoma on the toe of a teenaged girl.

An angiokeratoma is a benign vascular lesion that appears as one or more red to black papules with a verrucous surface. Histologically, it is defined by ectatic, thin-walled vessels in the papillary dermis, acanthosis with elongated rete ridges, and compact hyperkeratosis. Solitary angiokeratoma is one of five defined subtypes of angiokeratoma.

Indolent CD8+ primary cutaneous T-cell lymphoma involving the eyelid of an adolescent.

Primary cutaneous acral CD8+ T-cell lymphoma (PCACTL) is currently a provisional entity defined as a rare cutaneous proliferation of atypical CD8+ lymphocytes that preferentially involves acral sites and has a good prognosis. We present a case of primary cutaneous CD8+ T-cell lymphoma involving the eyelid of an adolescent male. The case shares features with PCACTL, including indolent clinical behavior and expression of CD68 in a Golgi-associated dot-like pattern; however, other features differ significantly from PCACTL as currently defined by the World Health Organization (WHO).

Alopecia universalis and onychodystrophy during treatment with adalimumab.

Alopecia universalis, the complete loss of body hair, during anti-tumor necrosis factor-alpha (TNF-α) biologic therapy is a rare occurrence that has infrequently been reported in the literature. In this case, a 50-year-old man with psoriatic arthritis exhibited alopecia universalis with concomitant onychodystrophy 3 months after initiation with adalimumab. Given the role of TNF-α in the pathogenesis of alopecia areata, it would seem unlikely for anti-TNF-α drugs to induce hair loss; however, it is hypothesized that alopecia areata and its variants may not be dependent on TNF-α and that other factors must be involved.
