Left radical nephrectomy: Tumor histologic type: Renal angiomyoadenomatous tumor (see Note). Note: The a clear cell papillary renal cell tumor and a renal angiomyoadenomatous tumor (""RAT"") (reval cell carcinoma with angioleiomyoma-like stroma). Although some authors consider RAT tumors to represent a pattern of clear cell papillary RCC we believe that this represents a dstinct entity. The combined findings ...confirm the diagnosis of renal angiomyoadenomatous (RAT) tumor. These tumors are also known as renal cell carcinoma within angioleiomyoma-like stroma. To date none of these tumors have developed metastases. Given the small number of reported cases we would consider these to have at worst a low malignant potential.

Left mandible resection: Malignant tumor, favor high grade sarcomatoid carcinoma. Please see comment.

Comment: Considering the focal stain with P63 and the consult from Mayo Clinic done on the previous biopsy, the diagnosis of sarcomatoid carcinoma is more likely.

Gross: left mandible resection...sectioning reveals a...mass that has replaced the majority of the mandibular bone and is at the medial, anterior lateral and posterior soft tissue margins and comes to within 2.4 cm of the anterior boney resection margin and 1.9 cm of the smooth articular temporal mandibular joint surface.

The combination of C411 and 8033/3 is impossible (with no override available).

Left mainstem bronchus mass excised: metaplastic endobronchial mucosa with submucosa containing an infiltrating poorly diff malignant tumor. Origin of tumor is not identified in overlying mucosa. IHC stains will be performed.

Addendum #1. IHC stains show well diff neuroendocrine neoplasm, favor carcinoid. Recommend sending this to expert in lung neoplastic pathologist.

Addendum #2. (lung path specialist) oncocytic neuroendocrine neoplasm.

Is this 8246 or 8290 or something else?

Left frontal mass biopsy diagnosis comment states: Given the synaptophysin and patchy CD34 staining of these cells, the possibility of ganglioglioma and pleomorphic xanthoastrocytoma is raised. Astroblastoma and ependymoma were considered given the perivascular pseudorosettes, however GFAP staining is quite limited against these tumors. Reticulin stain shows limited perivascular reticulin staining however. Nevertheless, the necrosis, mitotic activity and elevated mitotic activity would point to a malignant neoplasm. Given the neural and limited GFAP staining, a generic classification of neuroglial is provided.

This is the only available information. Further clarification or discussion with the physician or pathologist is not possible. Therefore, is this diagnosis of neuroglial tumor equivalent to that described in SINQ 20091037?

Left breast invasive lobular ca diagnosed 3/00 and treated with a lumpectomy, but with multiple positive margins; she received no post operative radiation or other medical treatment (unknown why). 10/08 core biopsy of "an area of distortion" near the scar site is positive for invasive lobular ca. The radiologist states "compatible with recurrence at her previous lumpectomy site" on an x-ray report.

One thought is that this should not be a new primary because the patient was never disease free (multiple positive margins) and the patient received incomplete treatment. Or should this be a new primary because the tumors are diagnosed more that 5 years apart?

Left Eye Conjunctiva, biopsy (01/23/2018): Conjunctival intraepithelial neoplasia moderate to severe. Is intraepithelial neoplasia moderate to severe the same as coding 8077/2?

Laterality is often not noted for these sella turcica meningiomas; therefore, Laterality is often coded as 9 (Unknown). Because the sella turcica appears to be a midline structure in the base of the skull, is Laterality code 5 (midline) more appropriate when additional information is unavailable?

Laryngeal intraepithelial neoplasia II-III is not included in the ICD-O-3.2 and, while the SEER Program Coding and Staging Manual (SPCSM) confirms this is reportable, neither the SPCSM nor the Solid Tumor Rules Manual provide the specific histology to use for LIN II or LIN III. Should this be coded as 8077/2 since this is most like a high grade squamous dysplasia?

LUL lobectomy: 1.7cm apical tumor, DX=mod well diff subpleural SCC, with involvement of pleural surface. 3 peribronchial LN neg and 2 AP window LNs neg. Stage T2N0.

1. No lymph node dissection or sampling was stated to be done

2. The lobectomy specimen contained the LNs

3. Scope of regional LN surgery is coded

Would the surgery to primary site code 30 or 33?

LUL lobectomy: 1.7 cm apical tumor, diagnosis: moderately well differentiated subpleural squamous cell carcinoma, with involvement of pleural surface. 3 peribronchial LN neg and 2 AP window LNs neg. Stage T2N0.

1. No lymph node dissection or sampling was stated to be done

2. The lobectomy specimen contained the LNs
