Skin from (a) dorsum left wrist and (b) left forearm, ulnar, near elbow. Clinical Diagnosis: Bowen disease versus basal cell carcinoma versus dermatitis Microscopic Description: (a) There is a mild hyperkeratosis and moderate epidermal hyperplasia with full-thickness atypia of squamous keratinocytes. Squamatization of the basal cell layer exists. A lymphocytic inflammatory infiltrate is present in the papillary dermis. Solar elastosis is present. (b) Nests, strands, and columns of atypical neoplastic basaloid keratinocytes grow down from the epidermis into the underlying dermal. Fibroplasia is present. Solar elastosis is noted.

The given question is incomplete as it lacks the major part of the question, however the correct question is as follows:

MD Specimen: Skin from (a) dorsum left wrist and (b) left forearm, ulnar area, near elbow.

Clinical Diagnosis: Bowen disease versus basal cell carcinoma versus dermatitis.

Microscopic Description: (a) There is mild hyperkeratosis and moderate epidermal hyperplasia with full-thickness atypia of squamous keratinocytes. Squamatization of the basal cell layer exists. A lymphocytic inflammatory infiltrate is present in the papillary dermis. Solar elastosis is present. (b) Nests, strands, and columns of atypical neoplastic basaloid keratinocytes grow down from the epidermis into the underlying dermis. Fibroplasia is present. Solar elastosis is noted. Pathologic Diagnosis: (a) Bowen disease of left wrist; (b) nodular and infiltrating basal cell carcinoma of left forearm, near elbow. Samantha Roberts, MD sr:bg

Answer these Questions:

1. In the specimen section, what does "skin on dorsum left wrist" mean?

2. What types of cells made up the inflammatory infiltrate?

3. What was the pathologist's diagnosis for the left forearm (look at pathologic diagnosis)?

4. Provide a brief description of Bowen disease, the pathologist's diagnosis for the left wrist.

1. The skin on the dorsum left wrist implies the outside of the wrist only inverse to the palm.  

2. Lymphocytes made up the incendiary penetrate.  

3. Nodular and penetrating basal cell carcinoma of left lower arm , close to elbow.  

4. Bowen ailment is a skin illness that happens because of development of anomalous cells in the epidermis layer of the skin. Since the irregular cells keep themselves to the epidermis just and don't spread away from it, so it's anything but a sort of cancer. But there are odds of disease being caused later. Red expanding patches are seen on the skin which on occasion bleed. They are caused because of high paces of sun introduction, by Human papillomavirus, or because of immunosupression. Treatment incorporates applying creams, for example, 5-FU to murder strange cells, cryotherapy, laser treatment and radiotherapy too.
