Basal cell carcinoma arising at the site of a previously irradiated infantile hemangioma.

We describe a case of a previously irradiated infantile hemangioma in a patient 1 year of age. At the age of 78, the patient presented with a pink, pearly plaque at the previously irradiated infantile hemangioma site and was found to have a nodular basal cell carcinoma. [Correction added on 30 August 2023, after first online publication: In the preceding sentence, patient age has been corrected in this version] This case highlights the rare, but long-term risks of radiation therapy for hemangiomas, but also presents an interesting historical vignette in dermatological treatments, with photographic documentation.

Bleeding complication following a shave biopsy in a patient taking ibrutinib.

Ibrutinib is an oral Bruton tyrosine kinase inhibitor approved for use in patients with B-cell malignancies and has been shown to increase progression-free survival in patients with chronic lymphocytic leukemia (CLL). Ibrutinib is known to increase bleeding risk in patients with CLL. We report a patient with CLL on ibrutinib who experienced significant and prolonged bleeding after a routine superficial tangential shave biopsy for suspected squamous cell carcinoma.

Float like a Butterfly, Sting like One Too.

Rash after contact with butterflies has not been previously reported in the medical literature to our knowledge. We describe potentially the first suspected case of a cutaneous reaction to the Compton tortoiseshell butterfly (Nymphalis vaualbum) in a young boy who developed urticaria after the modified hairs of the butterfly embedded within his finger. His urticaria improved through treatment with oral and topical steroids as well as systemic antihistamines.
