Case title: 26 year old male with a jejunal mass.
Clinical Summary:

A 26 year old male presented acutely with severe abdominal pain. Imaging studies showed a large mass encasing the jejunum, with associated small bowel obstruction. The patient had no significant prior medical or surgical history. Exploratory laparotomy was performed, and in addition to the large mass involving the mesentery of jejunum, multiple smaller pigmented and non-pigmented nodules involving peritonealized surfaces of the mesentery were identified. The jejunal mass was resected, along with all identifiable nodules. The gross specimen of the jejunal mass (measuring 16 cm) is shown in Figure 1 - the mass predominantly involved the mesentery, but extended through the wall of the small intestine into the mucosa. Intra-operative frozen sections of the mass are shown in Figures 2 and 3.  Additional representative images (permanent sections) of the mass and a seperate nodule are also provided (Figures 4-10).

Clinical Summary:

An 80 year-old male presented with a rapidly enlarging crateriform nodule on the scalp and a clinical suspicion of keratoacanthoma or squamous cell carcinoma. The patient's past medical history was unremarkable and he was otherwise healthy. A diagnostic curettage was performed. A subsequent re-excision showed scarring only with no evidence of residual tumor.
