Clobetasol is not cancer-directed treatment at this time.

Note: Question originally submitted in 2010. During 2014 review, this was checked and Clobetasol is still not cancer directed treatment for Mycosis Fungoides.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code to primary site to C447 [skin of leg]) per Rule PH25 and histology to 9702/3 [anaplastic large cell lymphoma, ALK-negative]. Per the Abstractor Notes section in Heme DB, these are the usual presentations for this disease. It also states this disease presents with peripheral node involvement and is often generalized with infiltrates in the bone marrow, liver, spleen, and extranodal tissue. Less frequently involved sites are lung, salivary gland and CNS.

Per PH25, code the primary site to the organ when the lymphoma is present in an organ (skin, right leg) and that organ's regional lymph nodes (inguinal). Distant lymph nodes or other organs may also be involved, but should be disregarded for coding primary site.

For cases diagnosed 2007 or later, this is a single primary.

In order to determine whether this case represents a single or multiple primary, you must first determine the correct histology code for the underlying tumor. Using rule H9, ignore the DCIS.

See Table 3 in the equivalent terms and definitions. Infiltrating lobular, tubular, and Paget are coded to a single histology code (8524/3). Our current multiple primary rules do not say infiltrating lobular and tubular and Paget are a single primary. This was an omission and will be corrected in a future revision. Thank you for bringing this omission to our attention.

Unless there are scans showing involvement of a lymph node or tissue other than the chest wall, the histology should be coded myeloid sarcoma [9930/3] and the primary site to C493 [soft tissue of chest wall]. Per Rule PH 30, use the Heme DB to determine primary site and histology when rules PH1-PH29 to not apply. Override the edit.

Per the Abstractor Notes section in Heme DB, for myeloid sarcoma [9930/3] the most frequently affected sites are skin, lymph nodes, gastrointestinal tract, soft tissue, and testis.

A papillary carcinoma of thyroid tissue in benign struma ovarii (mature cystic teratoma) is reportable.

These ovarian tumors contain a diversity of tissues including hair, teeth, bone, thyroid, etc. This reportable malignancy arose in thyroid tissue within the ovarian tumor. Code the primary site to ovary. Code to the actual organ in which the cancer arose. This will keep the case in the appropriate category for surgery coding, regional nodes, staging, etc.

Carcinoid, NOS, of the appendix diagnosed in 2015 or later is reportable.

For cases diagnosed prior to 2015

Carcinoids of the appendix are reportable when they meet any of the following conditions.

Note that the implants/involvement must be designated as malignant. Many benign tumors will spawn implants that are also benign. If implants are benign, this is not a reportable tumor.

Code the oncologist's clinical diagnosis of peripheral T-cell lymphoma.

The definition for this neoplasm is "A large group of lymphomas which we collectively refer to as peripheral T-cell lymphomas with the optional addition of "unspecified" to emphasize that these cases do not belong to any better defined entities. Attempts to distinguish between them on morphological basis have met with poor reproducibility."

Per the Abstractor Notes in the Heme DB: Patients present with peripheral LN involvement. The diagnosis of PTCL, NOS is made ONLY when other specific entities have been explored.

This fits your case; attempts to find a more specific disease (flow cytometry; BM biopsy) were negative and gave no further information that could be used to assign a more specific classification.

Per Rule PH30, use the Heme DB to determine the primary and code it to bone, NOS [C419]. Langerhans cell histiocytosis can occur as a solitary lesion, multifocal lesions, or multisystem disease. In this case, the patient has multifocal disease of the bone. The abstractor notes in the Hematopoietic DB were used as a reference for this answer.

The diagnosis of "myelodysplasia" is not reportable.

Myelodysplasia covers a group of disorders that result in the inability to produce enough healthy mature blood cells. Those disorders include: anemia, leukopenia, thrombocytopenia, MDS, refractory anemia, refractory anemia with excess blasts in transformation, refractory anemia with ring sideroblasts, refractory anemia with excess blasts, chronic myelomonocytic leukemia, acute myeloid leukemia. Follow-back to the physician is necessary to determine whether or not a particular case represents a malignancy.

"Myelodysplasia" is also listed in Appendix F: Non-Reportable List for Hematopoietic Diseases.
