A 75-year-old man with a three-year history of metastatic lung adenocarcinoma was diagnosed with cutaneous lymphangitic carcinomatosa of unique morphology. He was admitted to our hospital for right neck swelling, erythema, and failure to thrive. Skin examination demonstrated an indurated, thickened, firm, hyperpigmented plaque extending from the right neck and chest to the right ear, cheek, and eyelids. Skin biopsy demonstrated poorly differentiated adenocarcinoma, morphologically consistent with metastasis from the patient's known pulmonary adenocarcinoma and showed dermal invasion, perineural invasion, and involvement of dermal lymphatics. The diagnosis was an atypical presentation of cutaneous lymphangitis carcinomatosa from metastatic lung adenocarcinoma. This case presentation affirms that cutaneous lymphangitis carcinomatosa has a variety of atypical presentations, so physicians must maintain a high index of suspicion when evaluating cutaneous lesions in patients with known or suspected internal malignancy.

Establishing reliable nutrient requirements for individuals over the age of 65 years is a difficult task. Research on nutrient requirements in the aged is sparse and often contradictory. However, there are important clues in the literature suggesting that requirements for certain nutrients are altered with age and that preventable nutrient deficiencies exist. Energy expenditure and caloric intake typically decline with age. Unless nutrient density of the diet improves, a parallel decline in vitamin and mineral intake is inevitable. Deficiencies or suboptimal intakes of water-soluble vitamins, vitamin D, calcium, zinc, copper, chromium, and water are reported in groups of older adults. Marginal nutrient deficiencies in this population may easily go undetected and contribute to morbidity. [ABSTRACT FROM AUTHOR]

Abstract: Pseudocarcinomatous hyperplasia (PCH) is a reactive proliferation of the epidermis associated with CD30 + lymphoproliferative disorders. In this article, we report the case of a 42-year-old man who presented with a 10-year history of a solitary erythematous patch on the right thigh that progressed to an ulcerated, crusted plaque. Histologic examination revealed an infiltrate of atypical CD30 + lymphocytes consistent with primary cutaneous anaplastic large-cell lymphoma with overlying well differentiated keratinocyte hyperplasia akin to a well-differentiated invasive squamous cell carcinoma. This case demonstrates the phenomenon of pseudocarcinomatous hyperplasia mimicking features of invasive squamous cell carcinoma. It highlights the necessity of careful clinical correlation when diagnosing squamous cell carcinomas in younger patients on non-sun-exposed areas and the exclusion of accompanying known causes of pseudocarcinomatous hyperplasia., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Fixed drug eruption (FDE) is a cutaneous drug reaction that tends to recur in the same area (fixed location) upon re-exposure to the offending agent. We present a 48-year-old woman with FDE being treated for metastatic breast cancer with atezolizumab. We believe this is the first reported case of FDE secondary to atezolizumab.

Mastocytosis is a rare condition in which mast cells accumulate throughout various organs of the body-the most common subtype being confined to the skin. We present an unusual case of cutaneous mastocytosis localized to the unilateral breast of a young woman with partial involvement of the areola. Previously diagnosed as nipple eczema, the patient failed appropriate treatment with class III and IV topical corticosteroids. Given it was adult onset, failed appropriate treatment, and had an atypical clinical appearance, a biopsy was pursued that revealed mastocytosis in skin. This is another clinical diagnosis dermatologists may consider in their differential diagnosis of nipple dermatitis.

Background: The American Cancer Society (ACS) publishes guidelines on nutrition and physical activity to minimize health risks in cancer patients and survivors. Studies show that high adherence to such guidelines is associated with a decrease in overall cancer incidence and mortality. However, there are sparse data on adherence to the ACS guidelines in cancer survivors., Objective: The aim of this study was to describe adherence to the ACS guidelines in female cancer survivors who participated in an exercise intervention trial for 1 year., Methods: Perimenopausal and early postmenopausal female cancer survivors (n = 154) participated in a randomized controlled trial that examined the efficacy of an aerobic-resistance exercise intervention. In addition to body mass index and alcohol, diet and physical activity data were collected with 4-day diet records and the International Physical Activity Questionnaire. A scoring system was used to determine adherence to the ACS guidelines, with scores ranging from 0 (no adherence) to 8 (highest adherence)., Results: Mean total adherence scores for ACS guidelines for all intervention and control condition participants, most of whom had breast or gynecological cancers, were 4.2 (baseline), 4.9 (6 months), and 4.8 (12 months), suggesting moderate adherence. Physical activity levels improved in both groups; however, no significant change was observed for adherence to weight, dietary, or alcohol intake guidelines for either group., Conclusion: Findings indicate only partial adherence to the ACS guidelines, even for motivated cancer survivors participating in an exercise intervention study., Implications for Practice: Further research is needed regarding strategies and interventions to improve adherence to ACS guidelines.

The gastrointestinal (GI) and cutaneous systems are closely linked in origin. Skin manifestations are frequently seen as a part of different GI syndromes. Gastroenterologists play an important role in recognizing the symptoms, patient workup and arriving at appropriate diagnoses, often in consultation with dermatologists. This review discusses the diseases with both cutaneous and intestinal involvement. Hereditary polyposis GI cancers, hereditary nonpolyposis colorectal cancers (CRCs), hamartomatous disorders, and inflammatory bowel disease (IBD) are reviewed with emphasis on the genetic basis, diagnostic, histologic findings, screening modalities, and therapeutic options.

The Mediterranean-style diet (MedSD) has gained attention for its positive effects on health outcomes, including metabolic risk factors. However, it is unknown as to which components of MedSD interventions are most beneficial in reducing risk. The objective of this meta-analysis was to obtain effect sizes for metabolic risk factors and explain the variability across the current literature based on study design, sample, and diet characteristics. Six electronic databases were searched from inception until 9 February 2016. Data from 29 studies (N = 4133) were included. There were significant effects in favor of the MedSD for waist circumference, triglycerides, blood glucose, systolic blood pressure, and diastolic blood pressure (d+ = -0.54; d+ = -0.46; d+ = -0.50; d+ = -0.72; d+ = -0.94, respectively). The MedSD was significantly beneficial when the intervention was longer in duration, was conducted in Europe, used a behavioral technique, and was conducted using small groups. The traditional MedSD had significant beneficial effects on five of the six metabolic risk factors. Results from this study provide support for population specific dietary guideline for metabolic risk reduction.

Importance: Melanocytic neoplasms with prominent pigment synthesis mimicking equine melanoma represent a rare variant of biologically indeterminate or low-grade malignant melanocytic tumors in which the molecular profile and exact histologic classification are not established. Tumors with these characteristics rarely occur as congenital lesions. We performed genomic analysis of a congenital pigment synthesizing melanocytic neoplasm with indeterminate biological potential., Observations: The patient was a 5-month-old girl presenting with a 6-cm protuberant scalp mass, which had doubled in size since birth. Histologic examination showed heavily pigmented intradermal proliferation of large, epithelioid melanocytes with mild cytologic atypia, low mitotic activity, focal necrosis, and ulceration. RNA sequencing identified a novel ATPase, Ca2+ transporting, plasma membrane 4(ATP2B4)-protein kinase C-alpha (PRKCA) fusion transcript. The fusion resulted in an in-frame linkage of the PRKCA catalytic domain with the N-terminal of ATP2B4 and high expression of the PRKCA kinase domain. Break-apart fluorescence in situ hybridization showed PRKCA rearrangement, and reverse transcriptase-polymerase chain reaction confirmed the presence of the fusion transcript. The patient was alive and well, with no evidence of recurrence, at the 1-year follow-up., Conclusions and Relevance: To our knowledge, this is the first report of PRKCA fusions in melanocytic neoplasms. Future studies need to determine the frequency of PRKCA fusions in pigment-synthesizing melanocytic neoplasms.
