Scarring and Dyschromias in Fitzpatrick Skin Type IV-VI: A Review of Dermatologic Treatment Protocols.

IMPORTANCE: Managing chronic conditions is an essential aspect of dermatologic care, especially regarding the resolution of inflammatory dermatologic disease and recovery of skin lesions. Short-term complications of healing include infection, edema, dehiscence, hematoma formation, and tissue necrosis. At the same time, longer-term sequelae may consist of scarring and scar widening, hypertrophic scars, keloids, and pigmentary changes. This review will focus on dermatologic complications of chronic wound healing in patients with Fitzpatrick skin type (FPS) IV-VI or skin of color (SOC), with an emphasis on hypertrophy/scarring and dyschromias. It will focus on current treatment protocols and the potential complications specific to patients with FPS IV-VI. OBSERVATIONS: There are multiple complications of wound healing that are more prevalent in SOC, including dyschromias and hypertrophic scarring. These complications are challenging to treat, and current protocols are not without complications and side effects that must be considered when offering therapy to patients with FPS IV-VI. CONCLUSIONS AND RELEVANCE: When treating pigmentary and scarring disorders in patients with skin types FPS IV-VI, it is essential to implement a stepwise approach to management that is conscious of the side effect profile of current interventions.

Composite lymphoma of mycosis fungoides and cutaneous small B-cell lymphoma in a 73-year-old male patient.

Composite lymphoma of T-cell and B-cell type is uncommon, and the one occurring primarily on skin is extremely rare. Herein, we report a unique case of composite lymphoma of mycosis fungoides and cutaneous small B-cell lymphoma in a 73-year-old male patient. The patient presented with multiple erythematous patches, plaques, and nodules on the upper arms, scalp, and trunk. Four punch biopsies of arm and scalp lesions demonstrated lymphoid infiltrate in superficial to deep dermis with a characteristic zone distribution of T-cell and B-cell components. T cells were distributed in papillary and perifollicular dermis and displayed a larger size with convoluted nuclei, whereas B cells were small sized, assuming nodular infiltrate in mid-deep dermis with coexpression of CD5. Molecular test detected clonal rearrangement of both TCRG and IGH/K genes with identical amplicons for each gene in all 4 biopsies. Clinical staging revealed no extracutaneous lesions. A multidisplinary approach is emphasized to establish a definitive diagnosis.

Cosmeceuticals used in conjunction with laser resurfacing.

The use of laser resurfacing for cutaneous rejuvenation has become an important tool in the modern dermatologist's armamentarium. To ensure a successful outcome, proper preoperative and postoperative skin care is essential. Incorporating cosmeceuticals into the perioperative skin care regimen can promote a better overall patient experience by hastening postoperative healing, reducing common side effects, and enhancing overall rejuvenation. This article aims to explore the use of various cosmeceuticals in conjunction with laser resurfacing procedures. In particular, the overall mechanisms of action behind each selected therapy will be discussed, followed by a brief discussion of the existing literature on each agent's use with laser resurfacing. Theoretical considerations and a limited body of evidence suggest a potential benefit for the use of these agents in conjunction with laser resurfacing procedures; however, further placebo-controlled studies are needed to truly confirm these benefits.
