BACKGROUND: Patients with breast cancer frequently opt to undergo breast reconstruction after mastectomy. The timing and aesthetic outcome of the breast reconstruction may be affected by the need for radiation therapy (RT). Delayed-immediate autologous reconstruction (DIAR) is a novel surgical approach for patients in whom the need for adjuvant RT after mastectomy is preoperatively unknown. AIM: We sought to evaluate the difference in clinical outcomes, patient satisfaction, and cosmetic results between DIAR and patients who underwent delayed autologous reconstruction...

BACKGROUND: Reconstruction of nasal tip defects presents a significant challenge for plastic surgeons. The form, function, and aesthetic appeal of all nasal subunits must be addressed. The expanded paramedian forehead flap is a good choice for nasal reconstruction, providing similar texture, structure, and skin color, and high reliability. This article discusses the authors' modification of the expanded paramedian forehead flap in reconstructing defects on or around the nasal tip. METHODS: Twenty-two patients with nasal defects located on or around the nasal tip were treated in our institution...

Symbionts (e.g., endoparasites and commensals) play an integral role in their host's ecology, yet in many cases their diversity is likely underestimated. Although endoparasites are traditionally characterized using morphology, sequences of conserved genes, and shotgun metagenomics, host transcriptomes constitute an underused resource to identify these organisms' diversity. By isolating non-host transcripts from host transcriptomes, individual host tissues can now simultaneously reveal their endoparasite species richness (i...

A 41-year-old man from the state of Chhattisgarh, India, had a previous history of nasopharyngeal rhinosporidosis for 27 years, for which he had surgical intervention seven times, most recently endoscopically 2 months earlier. For the last 8 months, he had noticed skin lesions on the shoulders and forehead. Of interest was a history of bathing in ponds as a child. Examination revealed a soft, skin-colored, strawberry-shaped papule on the forehead (Figure 1A), a papule with a hemorrhagic crust on the left shoulder (Figure 1B), and a crusted friable plaque on the right shoulder (Figure 1C)...

BACKGROUND: Acne is very common skin condition. Most patients with acne will have a degree of scarring as a result of their acne. In patients with darker skin color the scarring can be further complicated by hyperpigmentation. Several treatment options can be used to improve acne scarring, however the problem of post acne hyperpigmentation is not often addressed. This study especially focus on the treatment of pigmented post acne scarring using skin microneedling. AIMS: The primary objective is to assess the improvement of pigmentation of acne scarring in patients with dark skin using microneedling...

When Donald Trump became president of the United States, I discovered that my clients who identified as Black saw me as a White clinician. With that came a host of nefarious attributions. To preserve therapeutic efficacy, and the genuine relationships with people about whom I cared, I had to distinguish myself from the president; thus, I learned not only how it feels to be seen through the bias of skin color but what I needed to do to identify as a person rather than a White person. "Welcome to my world," said one African American client...

Background: Human skin exists in a wide range of different colors and gradations, ranging from white to brown to black. This is due to the presence of a chemically inert and stable pigment known as melanin, which is produced deep inside the skin but is displayed as a mosaic at the surface of the body. Methods & Materials: In mammalian melanocytes, melanosome is a highly specialized organelle where melanin is synthesized. Melanin synthesis is controlled by tyrosinase, the vital enzyme in melanogenic pathway...

Granular cell tumors (GCTs) are rare and benign tumors that can occur at any anatomical site. GCTs are thought to originate from nerve cells, particularly Schwann cells. Their name derives from the fact that an accumulation of cytoplasmic lysosomes imparts the tumor with a granular appearance. They are most commonly observed in the oral cavity, skin and subcutaneous tissue, breast, and respiratory tract. Granular cell tumors rarely affect the gastrointestinal tract. We report a 58-year-old female with a past medical history of hypertension, mitral valve prolapse, and depression who presented for surveillance colonoscopy...

A proportion of cutaneous melanomas display neval remnants on histologic examination. Converging lines of epidemiologic and molecular evidence suggest that melanomas arising from nevus precursors differ from melanomas arising de novo. In a large, population-based study comprising 636 cutaneous melanomas subjected to dermatopathology review, we explored the molecular, host and environmental factors associated with the presence of neval remnants. We found nevus-associated melanomas were significantly associated with younger age at presentation, non-brown eye color, trunk site, thickness <0...

Amézquita et al. (2017) recently concluded that species of the Allobates femoralis group are toxic to mice at levels equivalent to syntopic alkaloid-containing poison frogs, which they attributed to the presence of alkaloids in skin secretions. However, the chemical composition of skin secretions was not analyzed, and here we present additional data supporting the absence of alkaloids in skin secretions of the Allobates femoralis group. Instead, we suggest the observed toxicity was caused by the anesthetic benzocaine, which was applied to the buccal cavity to euthanize frogs prior to skin removal...

PURPOSE: Most melanoma studies have been performed in the white population who exhibits the highest incidence rate due to their skin sensitivity to UV radiation. Previous publications have shown that young women (approximately under the menopausal age) exhibit higher incidence rates than men of the same age, and the causes are mostly attributed to their sun behavior or indoor tanning. In our recent publications, we suggested that higher risk in younger women was due to pathophysiological factors, such as hormonal impact, and thus this higher risk in young women should be shared across ethnicities regardless of their skin color or UV behavior...
