A case study on the dermatoscopic findings of Darier's disease in skin type VI.

We present dermatoscopic findings of long-standing, untreated Darier's disease (DD) in skin type VI that differs from current findings in literature. Robust hyperkeratotic polygonal-shaped plugs without a surrounding white halo and classic vascular features were noted on the anterior scalp, neck, axilla, midline trunk, and extensors. Through this case, we aim to contribute to emerging literature in describing features of DD under dermatoscopy to augment diagnosis.

Malignant chondroid syringoma: A systematic review.

Malignant Chondroid Syringomas (MCS) are very rare malignant tumours arising from cutaneous sweat glands, with only 51 reported cases in the literature. These tumours can metastasize and cause death if not treated adequately. While there are histological criteria to diagnose MCS tumours, there are no established criterion to determine which tumours are more or less likely to metastasize. A systematic review was performed to establish if any features of the primary MCS tumour are associated with risk of metastasis or patient mortality, as well as the efficacy of common treatment options. The literature search was performed using the Ovid Medline and Web of Science databases from inception through March 2020. This yielded 47 case reports corresponding to 51 unique patients. Statistical analysis of the collected data revealed none of the commonly accepted malignant histopathologic findings (including nuclear atypia and/or pleomorphism, mitotic figures, an infiltrative growth pattern, presence of satellite nodules, necrosis, and vascular and/or perineural invasion) of the primary tumour to be significantly more associated with metastatic risk or death. However, gross characteristics of the tumour, including size (greater than 5 cm) and truncal location of the primary lesion, were found to be associated with a higher risk of metastasis. The most effective treatment modality was wide local excision. Overall, primary MCS tumours, especially those greater than 5 cm or located on the trunk, should be treated with a wide local excision and followed closely to confirm no lesion recurrence or distant metastasis.

Systematic Review of Psychological Interventions for Quality of Life, Mental Health, and Hair Growth in Alopecia Areata and Scarring Alopecia.

Alopecia is associated with significant psychological burden. There is limited evidence on the use of psychological interventions in conditions of hair loss. This manuscript systematically reviews the current state of literature on psychological treatments for quality of life, mental health, and hair growth in various forms of alopecia. PubMed and Embase were searched with predefined inclusion and exclusion criteria. Reference lists were also examined for relevant studies. Nine articles met our criteria and are included in this review. Eight of the articles related to alopecia areata and one related to scarring alopecia. Mindfulness-based stress reduction (MBSR) was found to improve quality of life-related subjective symptoms, relationship impacts, anxiety, phobia, distress, and psychological symptom intensity. Alopecia-specific collocated behavioral health (CLBH) treatment showed a trend for psychosocial improvement in areas such as appearance shame, activity avoidance, negative emotions, and coping. Hypnotherapy was found to improve anxiety and depression, quality of life measures, and alexithymia. There was also some evidence for significant hair growth with hypnosis, but the data are mixed. Psychotherapy combined with immunotherapy led to more hair growth, and supported self-confidence. Finally, coping strategies modulated the subjective burden of alopecia, and were associated with disease improvement. Further research will be necessary to better establish the efficacy and optimal administration of these interventions in alopecia.

Buried treasure - the teaching potential of Kodachrome slides brought into the digital age.

Clinical images on Kodachrome slides have been used for decades in dermatologic education. While the technology to view these images is becoming obsolete, many training programs possess high-quality slides that have educational benefit. The University of Virginia Department of Dermatology possesses a collection of such slides that are currently being digitized and integrated into an educational software program. We present this article as a means of providing a uniform protocol for institutions with large Kodachrome collections to do the same. Our work has proven beneficial for both medical students interested in dermatology, allowing them to gain exposure to a variety of conditions that are not well emphasized in the general curriculum, as well as for dermatology residents, who use the program as a means to hone their diagnostic skills. Not only is there educational benefit to be derived from digitizing these slides but time is of the essence, as these slides can easily become damaged or degraded, and the technology needed to scan them is quickly becoming less available.

Methotrexate Monitoring in Dermatology- A Retrospective Cohort Study.

BACKGROUND AND OBJECTIVES: There are currently no evidence-based recommendations to guide lab monitoring in the first 90 days of methotrexate treatment. The purpose of this study was to determine whether certain monitoring practices or baseline patient characteristics were associated with increased risk of developing clinically meaningful lab abnormalities during the course of methotrexate treatment. PATIENTS AND METHODS: This retrospective cohort study analyzed 243 dermatologically managed patients taking methotrexate at the University of Virginia Health System. Odds ratios were used to analyze the risk of these patients developing lab abnormalities that result in a change in clinical management, referred to as clinically relevant events. Chi-square analysis was used to determine the optimal timing of methotrexate lab monitoring. RESULTS: A diagnosis of congestive heart failure (P=0.03), chronic kidney disease (P=0.03), and an initial low platelet count (P=0.008) increased the odds of developing a clinically relevant event at some point during methotrexate therapy. In the first 15 days following methotrexate initiation, only 1/114 (0.9%) lab draws resulted in discontinuation of the medicine, 1/114 (0.9%) resulted in maintenance of a stable dose, and 2/114 (1.8%) resulted in repeat laboratory testing. CONCLUSION: In the absence of concerning baseline patient characteristics, dermatologists may consider postponing initial lab monitoring until 15 days post methotrexate initiation.J Drugs Dermatol. 2021;20(3):320-325. doi:10.36849/JDD.5790.

Strictures, stones and cysts: an unusual cause of pancreatitis in a 20-month-old female child.

Choledochal cysts are dilations of the biliary tree that cause a variety of clinical symptoms and can lead to several types of complications. Choledochal cysts are most commonly diagnosed in childhood and frequently present with abdominal pain, jaundice and, in infants, an abdominal mass. Although the most concerning complication is malignant transformation of the cyst epithelium, other complications such as stone formation, acute pancreatitis and stricture can also occur and lead to patient morbidity. Treatment is aimed at not only relieving patient symptoms, but also decreasing a long-term cancer risk. We present a case of a child presenting with abdominal pain and vomiting secondary to a type IVa choledochal cyst complicated by acute pancreatitis, a common bile duct stricture and cystolithiasis.
