PathWays Case Study: November 21

​A 51-year-old man presented with dysphagia and was found to have a 9.0 cm, well-circumscribed submucosal mass in the distal esophagus. Endoscopic ultrasound-guided fine-needle aspiration was performed to evaluate the lesion. A Papanicolaou smear (Figure 1A) revealed the presence of bland-appearing spindle cells. This same spindle cell proliferation was also observed within the cell block material (Figure 1B), and immunohistochemical stains were performed to characterize the lesion, including: KIT (Figure 1C), smooth muscle actin (Figure 1D) and desmin (Figure 1E).

After three months of medical therapy, the esophageal lesion continued to increase in size and the patient had no improvement in his symptoms. The decision was made to proceed to partial esophagogastrectomy. Upon resection, a large submucosal mass was present in the mid-lower esophagus and it showed a tan and glistening cut surface (Figure 2).Microscopically, it displayed spindle cells arranged in fascicles (Figure 3A), and immunohistochemical stains for KIT (Figure 3B), desmin (Figure 3C), and DOG-1 (Figure 3D) are performed.

Thank you very much for your question,may i kindly request for more case study as we go along.

What can a person do if she has no control over urinating. She does not know when she has to urinate. Therefore she wits herself. This happens during the day and into the night.
