What therapies have you most effective in managing the pruritus associated with lichen amyloid?
Lichen amyloidosis itch would respond extremely well to Nemolizumab. See the report by Talias group. Makes sense as we found that IL31R and OSM are key factors in pathogenesis.Gabriela Soto-Canetti et al., JAAD Case Reports 2025If Nemo is not available, MTX works.Methotrexate for the Treatment of Re...
How would you approach management of a large, fungating squamous cell carcinoma of the auricle if surgical management is not desired by the patient?
For a tumor this size and with cartilage invasion, I would recommend starting with induction cemiplimab to best response (generally 4-6 cycles), followed by consolidative RT, generally electrons. Prior to starting the immunotherapy, I would stage the neck with a contrast CT scan, as tumors of this s...
How do you approach patients who continue to experience pruritus and ongoing concern for persistent scabies despite having completed appropriate treatment?
Pruritus can not uncommonly continue in patients for 6 weeks or more after infestation is managed. High-dose antihistamines may be of some benefit. Consider if there is an ongoing untreated exposure that the patient has not thought of or cannot/will not share with you. Not all people infested with s...
How would you manage a patient who presents with hair loss that began after they started a GLP-1 inhibitor?
If it fits with telogen effluvium, I recommend monitoring. Many patients will improve after this initial shedding and will not have long-term shedding or long-term thinning. If there is any underlying androgenetic alopecia or pattern hair loss, then starting treatment as you normally would is also r...
What is your approach to tapering off rituximab in a patient with pemphigus who seems to be remission?
When a patient has achieved clinical remission and also has low-titer antibodies to desmoglein 1 and 3 (with the exception of patients who may have non-pathogenic antibodies, which can be trended over time), we discuss tapering rituximab. There are, of course, pemphigus patients, especially those wi...
How do you counsel patients with pemhigus on the main safety benefits of a low or ultra low dose rituximab regimen?
Although I read this article with interest and an open mind, I have not adopted ultra-low dose rituximab into my clinical practice of treating pemphigus patients for several reasons. The author's conclusions may very well end up being correct over time, but there are too many concerns with the study...
What do you view as the optimal use and timing of cemiplimab in high risk CSCC?
Increasingly, neoadjuvant cemiplimab has become our preferred approach for many patients with resectable high-risk CSCC, and this is consistent with what several high-volume centers are now doing. The high pathologic response rates, durable recurrence-free survival in responders, and meaningful surg...
Would you continue cemiplimab adjuvantly, following resection of initially unresectable cutaneous squamous cell carcinoma treated with downstaging immunotherapy?
This is a challenging question because, as you know, we have no randomized data to address it. I generally do not continue immune checkpoint therapy after resection of SCC skin. However, given the adjuvant data in melanoma and the high efficacy of anti-PD1 in skin SCC, I do think it is reasonable to...
What are your favorite modalities for preventing hypergranulation tissue?
Although exuberant granulation tissue is not totally preventable nor predictable, persistent inflammatory impetus, such as from hairs embedded in a surgical closure, or spitting suture reactions, can stimulate excess granulation tissue. Careful avoidance of trapped hairs as well as burying absorbabl...
How do you treat gram-negative folliculitis in a transplant patient on sirolimus who cannot use isotretinoin due to drug interactions?
The most critical issue with these infections in the immunocompromised host is the correct identification of the organism and its sensitivities to allow appropriate selection and course of antibiotics. Because the infection is deep in the hair follicle and the patient will shave the area, there is a...
