Hepatosplenic gamma/delta T-cell lymphoma in bone marrow. A sinusoidal neoplasm with blastic cytologic features.

abstract：:Squamous cell carcinoma (SCC) is by far the most common malignancy of the upper aerodigestive tract. Most conventional-type SCCs do not present the surgical pathologist with diagnostic difficulty. Certain variants, however, can histologically mimic benign and other malignant diseases. In such cases, correct diagnosis ...
