Recurrent trichilemmal carcinoma with a large cutaneous horn formation.
We describe an unusual case of trichilemmal carcinoma accompanied by a large horn formation in a 79-year-old man who presented with a brown tumor mass including a 15-cm-long horn on the vertex for one and a half years. Two months after the surgical removal of the primary tumor, the tumor recurred with a dimension 10x8x8 cm. ⋯ After 2 years, the patient had not shown any recurrence or metastases. We highlight the features that distinguish trichilemmal carcinoma from the other malignant tumors, such as squamous cell carcinoma, basal cell carcinoma, nodular melanoma, or keratoacanthoma.

Intravenous immunoglobulin-associated renal failure in a patient with post-transfusion purpura.
Intravenous immunoglobulin (IVIG), initially developed for immunodeficiency disorders, has now been used for multiple autoimmune diseases and infections. These are generally well tolerated, with few adverse effects. Acute kidney injury has been described in very rare instances. ⋯ The etiology remained elusive even after an extensive workup. Renal biopsy was done finally, which showed findings suggestive of osmotic nephropathy that was traced to the sucrose used as a stabilizing agent in the IVIG. In light of the increasing use of IVIG, it is therefore highly recommended that clinicians are well aware of this side effect of IVIG.
