Article Synopsis
  • Pilomatrix carcinoma (PMC) is a rare and aggressive hair follicle tumor with high recurrence and metastasis risks, often stemming from benign pilomatricoma or arising independently.
  • A study analyzed various surgical treatments for PMC by reviewing 257 articles from major databases, ultimately including 50 relevant studies, highlighting the effectiveness of different surgical methods.
  • The findings revealed that Mohs micrographic surgery (MMS) had no recurrences in 17 treated cases, while surgical excision resulted in a 34.5% recurrence rate, suggesting that MMS is a superior option to minimize recurrence and preserve tissue.

Article Synopsis
  • Chronic hand eczema (CHE) is a common skin condition that is hard to treat, but the drug dupilumab, known for treating atopic dermatitis, shows promise for CHE as well.
  • A review of 22 studies involving 374 patients revealed that 80.3% experienced partial or complete improvement within 4-16 weeks of starting dupilumab, with effects often lasting beyond the studies.
  • While dupilumab proved effective for various CHE subtypes, it was particularly successful for dyshidrotic and vesicular forms, but less so for hyperkeratotic eczema; the most common side effects included conjunctivitis and mild skin reactions.

Article Synopsis
  • - Mohs micrographic surgery is a preferred method for treating high-risk skin cancers, offering low recurrence rates and preserving tissue, especially in sensitive areas like the face and genitals.
  • - A systematic review was conducted on the effectiveness of Mohs surgery for skin cancers related to human papilloma virus (HPV), examining 33 studies and a total of 700 cases.
  • - The overall recurrence rate after Mohs surgery for HPV-associated skin cancers was 8.2%, with specific rates for different types, and patients generally reported good functional and cosmetic outcomes.

We present the case of a 55-year-old woman with a 10-day history of a rapidly progressing generalized rash. History was significant for recent increase in turmeric supplement dose. Clinical presentation was notable for diffuse plate-like yellow scaling of the scalp with lesser involvement of the ears.

Purpose: In this review article, we sought to elucidate how the social determinants of health, including socioeconomic status, education, neighborhood or physical environment, access to healthcare, and race/ethnicity, affect the likelihood of receiving immunotherapy, a novel and expensive treatment for melanoma.  Methods: The PubMed database was queried up to May 2023, for studies pertaining to health disparities in melanoma, including studies examining the utilization of immunotherapy agents for the treatment of melanoma across various social determinants of health.

Results: Disparities in the utilization of immunotherapy exist across various social determinants.

This study is to report the demographics, incidence, and patterns of spinal injuries associated with border crossings resulting from a fall from a significant height. A retrospective cohort study was performed at a Level I trauma center from January 2016 to December 2021 to identify all patients who fell from a significant height while traversing the U.S.

We present a case of a 40-year-old female seen on the inpatient general surgery service in consultation for a suspected abdominal wall abscess or seroma. The history and examination were consistent with a diagnosis of hidradenitis suppurativa. The patient had a 25-year history of similar lesions present since her teenage years, not properly investigated and diagnosed, despite presenting with symptoms in multiple clinic and hospital settings since disease onset.

Prurigo nodularis (PN) is a quintessential neurocutaneous condition characterized by neural sensitization and intractable itch leading to intense scratching. This causes the formation of nodules with epidermal thickening and further release of pro-inflammatory mediators that recruit immune cells and increase dermal nerve proliferation and hypertrophy perpetuating the itch-scratch cycle. Those with PN have a significant quality-of-life (QoL) burden due to itch, anxiety, and sleep disturbance.

The diagnosis of solitary mastocytoma is usually made clinically, however, atypical presentations may obscure the diagnosis. We present a unique case of solitary cutaneous mastocytoma in an 11-month-old male initially misdiagnosed as atopic dermatitis; the diagnosis was obscured due to the development of an allergic contact dermatitis most likely secondary to topical medications that were being applied to the lesion. The diagnosis of solitary cutaneous mastocytoma is made based on lesion morphology, Darier's sign, and lack of systemic involvement.

Purpose: The incidence of cutaneous melanoma is rising, and Melanoma related deaths are highest among people aged 65-74. Herein, we aim to understand the impact of novel and established melanoma treatment methods on CM related mortality and all-cause mortality. We further compared these effects among Hispanic and non-Hispanic Whites (NHW).

Drug conjugates have become a significant focus of research in the field of targeted medicine for cancer treatments. Peptide-drug conjugates (PDCs), a subset of drug conjugates, are composed of carrier peptides ranging from 5 to 30 amino acid residues, toxic payloads, and linkers that connect the payload to the peptide. PDCs are further broken down into cell-penetrating peptides (CPPs) and cell-targeting peptides (CTPs), each having their own differences in the delivery of cytotoxic payloads.

The era of personalized cancer therapy is here. Advances in the field of immunotherapy have paved the way for the development of individualized neoantigen-based therapies that can translate into favorable treatment outcomes and fewer side effects for patients. Addressing challenges related to the identification, access, and clinical application of neoantigens is critical to accelerating the development of individualized immunotherapy for cancer patients.
