Assessment of Pain, Healing Time, and Wound Contraction in Postoperative Auricular Defects Healing Secondarily With and Without the Use of a Porcine Xenograft, a Pilot Study.

Background: Postoperative auricular defects heal well with secondary intention healing (SIH); however, potential complications include postoperative pain, perichondritis, and chondritis.

Objective: To compare postoperative pain and wound healing in auricular defects healing by secondary intention with and without the placement of a porcine xenograft.

Materials And Methods: Twenty-one subjects were enrolled in the study.

Management of surgical soft tissue defects of the lower extremities.

Management of post-operative soft-tissue defects on the lower legs is challenging owing to arterial and venous insufficiency, poor skin quality including epidermal and dermal atrophy, insufficient tissue laxity, and increased risk of infection. This paper highlights the management of post-operative soft-tissue defects on the lower extremity that cannot be closed primarily or by reconstruction with a local flap. A systematic review of the literature was performed using the National Library of Medicine (NLM) PubMed online database.

Family history of psoriasis, psychological stressors, and tobacco use are associated with the development of tumor necrosis factor-α inhibitor-induced psoriasis: A case-control study.

Background: Tumor necrosis factor-α inhibitor-induced psoriasis (TNFI psoriasis) is a paradoxical reaction characterized by development of a psoriasiform rash that mimics psoriasis vulgaris. Temporal onset variability and low incidence rates suggest that underlying risk factors or outside triggers have a role in TNFI psoriasis initiation.

Objectives: We aimed to identify underlying risk factors and outside triggers associated with TNFI psoriasis onset.

Metastatic Multiple Myeloma to the Skin.

Cutaneous involvement of multiple myeloma (MM) is uncommon, typically occurs in late stage disease, and is a poor prognostic indicator with an approximate eight month median survival. We present a 51-year-old man with relapsed lambda light chain MM who developed abrupt asymptomatic skin metastases. Biopsy revealed a dermis replete of atypical plasma cells, positive for CD138 and CD45.

Basal cell carcinoma with intravascular invasion: A case report and review of the literature.

The significance of basal cell carcinoma (BCC) invading the intravascular space is unknown. We report a case of an infiltrative BCC on the scalp that showed evidence of both intravascular and perineural invasion. The tumor locally recurred in the bone marrow space 4.

TNF-α inhibitor-induced psoriasis: A decade of experience at the Cleveland Clinic.

Background: Tumor necrosis factor-α (TNF-α) inhibitor (TNFI)-induced psoriasis remains poorly understood despite having been described 15 years ago. As TNFIs often provide life-changing patient benefits, understanding effective treatments for TNFI-induced psoriasis is important.

Objective: We characterized a cohort of patients with TNFI-induced psoriasis whose psoriasis was specifically diagnosed and managed or comanaged by dermatologists at a single tertiary care institution over a 10-year period.

Differentiating Intralymphatic Histiocytosis, Intravascular Histiocytosis, and Subtypes of Reactive Angioendotheliomatosis: Review of Clinical and Histologic Features of All Cases Reported to Date.

Reactive angioendotheliomatosis (REA) is a rare benign angioproliferative condition of the skin, which has been noted to occur in patients with a variety of underlying systemic diseases. Histopathologically, this condition is characterized by vascular proliferation, and endothelial cell hyperplasia within the lumina and around dermal vessels, without significant cellular atypia. Since the first case of RAE was reported in 1958, multiple histologic patterns of benign cutaneous vascular proliferations with similar clinical presentations to RAE have been described in the literature and have been proposed as subtypes of the originally described condition.

Type I Cutaneous Meningioma (Rudimentary Meningocele) With Intradural Attachment to the Phylum Terminale.

Cutaneous meningiomas (CM) are a small subset of meningiomas, further classified into three subtypes. The authors present a 15-year-old male with a symptomatic congenital type I CM and describe the histopathological and immunohistochemical findings. To the authors' knowledge, this is the first report of an extraspinal lumbar type I CM with intradural attachment to the phylum terminale.

Benign Glandular Schwannoma With Ancient Change.

Benign glandular schwannomas are rare and should be distinguished from malignant peripheral nerve sheath tumors with similar divergent tissue differentiation. The authors present a benign glandular schwannoma with ancient change that developed in the subcutis of a 46-year-old man's posterior calf. He lacked stigmata of neurofibromatosis type 1 (NF1).
