For cases diagnosed 2007 - 2020

Assign code 8720/3 [Malignant melanoma] for melanoma with Spitzoid features, Spitzoid variant of nevoid melanoma, melanoma arising in Spitz nevus, or Spitzoid melanoma. The WHO Classification of Tumors groups these with Nevoid melanomas and codes them to 8720/3.

According to WHO, "Nevoid melanoma is a subtype of malignant melanoma of the skin that is distinctive in that the primary lesion mimics many of the architectural features of a common compound or intradermal nevus ... or a Spitz nevus... These lesions are defined not as atypical nevi, but as melanomas because they involve the dermis and have the potential for metastasis."

For cases diagnosed 2007 or later, code 8523 [infiltrating duct mixed with other types of carcinoma] for

1. Infiltrating ductal carcinoma, mucinous type and

2. Infiltrating ductal carcinoma with features of tubular carcinoma

The infiltrating ductal types in Rule H12 are listed (8022, 8035, 8501-8508) and do not include mucinous or tubular. We cannot use this rule. The first rule that applies to these single tumors is H17, code to 8523. If you look up 8523 in the numerical morphology section of ICD-O-3, you will see similar examples included in the definition of this code.

For cases diagnosed 2007 or later, assign 8077/2 [Squamous intraepithelial neoplasia, grade III] for VIN III diagnoses, regardless of the type. According to the WHO Classification of Tumours (page 319), "VIN is predominately of the warty or basaloid types...."

Use the multiple tumors module to determine the histology code for VIN. Rule H21 applies.

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Assign CS extension code 20

[Extension from other parts of lung to main stem bronchus, NOS

(EXCLUDES superficial tumor as described in code 11)

Tumor involving main stem bronchus greater than or equal to 2.0 cm from carina (primary in lung or main stem bronchus)].

A right middle lobe tumor that extends to the bronchus intermedius is one that is extending to the main stem bronchus from another part of the lung. The bronchus intermedius is the lower part of the main stem bronchus on the right. It is more than 2.0 cm away from the carina.

For cases diagnosed 2007 or later:

When the final diagnosis indicates that the microscopic section contains the detailed diagnosis, use the microscopic description to code the histology.

Otherwise, code from the final diagnosis only and not from the microscopic description. The final diagnosis is usually the pathologist's conclusion after consideration of the various choices listed in the microscopic description. The histology code should represent the pathologist's final conclusion.

If the inflammatory myofibroblastic tumor is primary in one of the sites specified below and diagnosed 1/1/2004 or later, it is reportable.

Reportable brain and CNS tumors are any benign and borderline primary intracranial and CNS tumors with a behavior code of /0 or /1 in ICD-O-3 diagnosed 1/1/2004 and later, of the following sites:

• Cerebral meninges C700
• Spinal meninges C701
• Meninges, NOS C709
• Cerebrum C710
• Frontal lobe C711
• Temporal lobe C712
• Parietal lobe C713
• Occipital lobe C714
• Ventricle, NOS C715
• Cerebellum, NOS C716
• Brain stem C717
• Overlapping lesion of brain C718
• Brain, NOS C719
• Spinal cord C720
• Cauda equine C721
• Olfactory nerve C722
• Optic nerve C723
• Acoustic nerve C724
• Cranial nerve, NOS C725
• Overlapping lesion of brain and central nervous system C728
• Nervous system, NOS C729
• Pituitary gland C751
• Craniopharyngeal duct C752
• Pineal gland C753

For cases diagnosed 2007 or later:

The pathology report takes precedence over the other information when there is a discrepancy. Based on the information available, only the left thyroid lobe was removed 11/95.

Use the 2007 MP/H rules to evaluate new tumors. If the 3/08 diagnosis represents a new tumor, use the MP/H rules. If the diagnosis in 3/08 is not new tumor, the MP/H rules do not apply.

For this case, a new tumor in 3/08 would be a new primary using rule M10 for Other Sites.

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Assign code 005 [0.5 cm] in this case. According to the General Instructions for CS tumor size, it is acceptable to code an aggregate size stated by the pathologist (see instruction 4.i).

For cases diagnosed 2007 or later:

Because there was cytologic confirmation of cancer, for this case only count the spiculated opacities as tumors. Abstract as a single primary using Rule M1. Note 2 under lung rule M1 applies to this case.

Code the histology as 8041 [small cell carcinoma] per rule H10.
