This is a single primary per Rule M2 which indicates to abstract a single primary when there is a single histology. Code the histology to 9590/3 [lymphoma] and the primary site to C629 [testes. Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal lymphomas occur in multiple sites, particularly in paired sites.

Primary site: What primary site do I assign to a Squamous Cell Carcinoma of the parapharyngeal space when there is no other info available regarding a more definitive site within the parapharyngeal space? Each physician involved with the case states the primary site is the parapharyngeal space. This is a patient who was diagosed and treated elswhere and was seen at our hospital several months later for a radical neck dissection for suspected lymph node mets.
Assign C139 for a primary originating in the parapharyngeal space. This space contains part of the parotid gland, adipose tissue, lymph nodes, nerves, arteries and veins.
Primary site/Histology--Heme & Lymphoid Neoplasms: How are these field coded when a biopsy of a substernal mass and the pericardium show T-cell lymphoblastic lymphoma/leukemia, the CT scan showed mediastinal and hilar adenopathy and no bone marrow biopsy was done?
Code the histology to 9837/3 [T lymphoblastic leukemia/lymphoma].
To determine the primary site for leukemia/lymphoma histologies, first go to Module 4. Per Rule PH8, code the primary site to the site of origin when lymph nodes, tissue or organs are involved. To determine a more specific histology, go to Module 7, rules for coding primary site for lymphomas. Per Rule PH20, code the lymph node region when multiple lymph node chains within the same region are involved. Mediastinal and hilar lymph nodes are intrathoracic lymph nodes. The substernal mass is also intrathoracic and is presumed to be a lymph node mass which involved the pericardium. For this case, code the primary site to C771 [Intrathoracic lymph nodes].

MP/H Rules/Histology--Colon: How do you use Rule H5 or H6 to code "moderately diff adenoca with mucinous component"?
For cases diagnosed 2007 or later, code the histology 8140 [Adenocarcinoma]. Rule H6 applies because the final diagnosis is not "mucinous adenocarcinoma" and the percentage of mucinous adenocarcinoma is not stated.
Rule H13 does not apply because "component" is not a term that indicates a specific histology.
Reportability--Skin: Is atypical intradermal smooth muscle neoplasm (AISMN) of the skin reportable? The comment on the path report states: Atypical intradermal smooth muscle neoplasm (AISMN) was previously termed "cutaneous leiomyosarcoma."
Atypical intradermal smooth muscle neoplasm (AISMN), previously termed "cutaneous leiomyosarcoma," is not reportable. It is classified as a borderline, /1, neoplasm.
Primary site--Heme & Lymphoid Neoplasms: What is the primary site code for a primary effusion lymphoma if the patient has multiple regions that are positive (e.g., pleural and pericardial effusion and the pleural fluid) for lymphoma?
Per the Abstractor Notes in the Heme DB, primary effusion lymphoma (PEL) is unusual in that the majority of cases arise in body cavities, such as the pleural, pericardial, and peritoneal cavities. Because there are no ICD-O-3 codes for the pleural space, pericardium, or peritoneal cavity, code the primary site to pleura C384 when the neoplasm arises in the pleural cavity, to pericardium C380 when it occurs in the pericardium, and to peritoneal cavity C482 when it occurs in the peritoneum.
Typically only one body cavity is involved. However, if multiple regions are positive for PEL as in this case, code the primary site to C809 per Rule PH27. Rule PH27 indicates one is to code the to primary site C809 when there is no evidence of lymphoma in lymph nodes AND the physician in the medical record that he/she that the lymphoma in an

Laterality: Why is a code 5 for laterality midline only allowed for certain sites of brain and skin? I have a nasal cavity tumor and the path report specifically says "Tumor laterality: midline". What is the correct laterality code here?
Assign laterality code 9 for midline nasal cavity tumor. We will investigate this issue further.
Reportability--Heme & Lymphoid Neoplasms: Is the term "thrombocytopenia" equivalent to the term "refractory thrombocytopenia" and should be a subsequent primary if it follows a treated diagnosis of pancreatic cancer?
Thrombocytopenia NOS is not a reportable diagnosis per Appendix F. Thrombocytopenia and Refractory Thrombocytopenia are not the same disease.
Thrombocytopenia is caused by a decreased number of platelets in the blood. Non-malignant causes include disseminated intravascular coagulation (DIC), drug-induced non-immune thrombocytopenia, drug-induced immune thrombocytopenia, hypersplenism, immune thrombocytopenic purpura (ITP), thrombotic thrombocytopenic purpura, and infections of the bone marrow.

Primary Site--Melanoma: How would this field be coded for a pleural effusion consistent with metastatic melanoma and "no skin lesions?"
Code primary site as C44.9 [Skin, NOS]. ICD-O-3 does not list a suggested site code for 8720/3 because melanoma can arise in other parts of the body. However, C44.9 [Skin, NOS] is the default when the primary cannot be found.
