12/3/2020 Pathology: AML: Blasts 40% of nucleated cells. CD45 positive, CD34 negative, CD 117+,

CD13 positive, CD33 positive in 59.6% and HLA-DR was dim and myeloperoxidase was dim.

Cytogenetics normal karyotype. The next generation sequencing detected IDH 2p.(R172K)c515>A.

Because this was AML NOS, we consulted with the physician. The physician stated the patient had AML with recurrent genetic abnormalities"and the basis for the diagnosis was the IDH-2 mutation identified on Next Generation Sequencing. We assigned 9896/3, based on the physician's interpretation of the pathology. This histology is being questioned.

12/22/11 Bladder biopsy: myeloid sarcoma,

12/22/11 Bone marrow biopsy: acute myeloid leukemia.

Presenting symptoms were urological with three month history of painful hematuria and hydronephrosis with solid mass of bladder.

Prior to biopsy hem/onc states bladder mass of unknown pathology. CBC revealed peripheral blasts and Auer rods -- presumed diagnosis of acute myeloid leukemia (AML). No statement from physician as to where disease originated.

12/1993 Bone marrow biopsy: Chronic myeloid leukemia t(9;22) (q34;q11).

09/2011 Bone marrow biopsy: Abnormal cytogenetic & FISH support persistent involvement by chronic myelogenous leukemia.

12/2011 Peripheral blood, flow cytometry: Involvement by acute myeloid leukemia arising in chronic myelogenous leukemia (CML, blast phase, 30% blasts by manual diff.).

Is the 12/2011 diagnosis a new primary? If not, why don't Rules M8-M13 apply when the Heme DB Abstractor Notes section for CML indicates that when there is a chronic, accelerated and blast phase that develops later in the course of the disease, change the histology code to the more specific diagnosis?

12/02 Baseline mammogram: spiculated mass with associated marked retraction located in UOQ lt breast. This has the markings of malignancy. Several microcalcifications in outer aspect of rt breast. BI-RADS 5 higly suggestive of malignancy.

12-19-19 Transurethral resection of bladder tumor pathology revealed high-grade papillary urothelial carcinoma with focal glandular and neuroendocrine features; Pathology Overread: High-grade papillary urothelial carcinoma with focal glandular and neuroendocrine differentiation. Carcinoma invades muscularis propria pT2.

Histology 8130

01/20/20 to 07/01/20, completed 6 cycles of gemcitabine/cisplatin.

07/30/20 Robotic radical cystoprostatectomy with bilateral pelvic lymph node dissection, open ileal conduit pathology revealed carcinosarcoma, invading perivesical fat, no lymphovascular invasion, negative margins. ypT3bN0M0 disease; Pathology Overread: Carcinosarcoma arising in association with high-grade papillary urothelial carcinoma.

Histology 8980/3 or is there another histology that should be used?

11/8/2013 Rt orchiectomy: teratoma with somatic type malignancy (adenocarcinoma).

5/2/2014 Abdominal mass excision: metastatic teratoma involving matted lymph nodes. Patient age at diagnosis is 31.

Per web search, a teratoma with somatic type malignancy is a rare type of tumor. Should the histology be coded to 8140/3? This seems to conflict with SINQ 20120085, which indicates a testicular mature teratoma in an adult is malignant, and in this example, it was also the portion of tumor that metastasized.

11/7/12 Peripheral blood flow cytometry: small population of clonal CD5- CD10- B-cells consistent with a B-cell lymphoproliferative process.

1/16/13 Bone marrow final diagnosis: co-existent systemic mastocytosis and lymphoplasmacytic neoplasm.

B-cell component of lymphoplasmacytic neoplasm constitutes 20% of bone marrow cellularity and the plasma cell component approximately 20%. The differential diagnosis includes marginal zone lymphoma with plasmacytic differentiation and lymphoplasmacytic lymphoma.

Flow cytometry: kappa monotypic B-cells and plasma cells.

Comment: Co-existence of systemic mastocytosis and mature B-cell lymphoma meets the criteria for Systemic mastocytosis with Associated Clonal Hematological Non-Mast Cell Lineage Disease (SM-AHNMD).

From our physician's progress note: KIT-D816V-positive, CD117+/CD25+ /SM-AHNMD(40% of the nucleated cells as spindled mast cells) but also seemingly two distinct lymphoid neoplasms, a CD5-negative/CD10-negative B-cell lymphoproliferative neoplasm consistent with occupying another 20% of the nucleated marrow space, together with an IgG-kappa-restricted (non-reportable diagnosis) occupying another 20% of the nucleated marrow space (and an accompanying 2.0 g/dl M-spike without hypercalcemia or anemia).

11/24/20 Adnexal mass, cyst fluid: Positive for malignant cells. Clusters of inhibin-positive, CK7-negative cells, consistent with adult granulosa cell tumor cells. Groups of inhibin-negative, CK7-positive epithelial cells consistent with serous borderline tumor cells. Peritoneal washing: Positive for malignant cells. Small groups of inhibin-positive, CK7-negative cells, consistent with adult granulosa cell tumor cells.

A. Left ovarian mass: Adult granulosa cell tumor (AGCT) of ovary (see note). pTNM Stage: pT1c3 pNX - Serous borderline tumor (SBT) of ovary (see note). pTNM Stage: pT1a pNX. Fallopian tube; unremarkable.

B. Right ovary: - Serous cystadenofibroma of ovary. Fallopian tube; unremarkable.

C. Left pelvic wall nodule: Fibro-calcified nodule, consistent with necrotic appendix epiploica.

D. Uterus (hysterectomy): Uterine leiomyomas. Endosalpingiosis of uterine serosa and paracervical tissue. Atrophic endometrium.

Note: The left ovarian mass is involved by a combined adult granulosa cell tumor and a serous borderline tumor. The AGCT mainly involves the thick-walled cystic area while the SBT the thin-walled cyst/s. The 2 neoplastic elements do, however, demonstrate areas of intimate and close intermingling. From the current literature, it appears that, based on FOXL2 mutation, the AGCT component of combined AGCT and ovarian epithelial tumors is either a true neoplastic processes or an AGCT- like proliferation morphologically indistinguishable from AGCT. To further evaluate the nature of the AGCT component, a FOXL2 analysis is in progress and an addendum will follow.

11/2003 CT chest: 2 cm LLL mass should be considered carcinoma until proven otherwise.

2/2004 CT Chest: stable LLL mass still consistent with primary or metastatic lung neoplasm

11/2004 CT chest: LLL mass suspicious for slow growing carcinoma

3/2005 FNA L lung: atypical cells

4/2005 L lobectomy: well-diff adenocarcinoma

11/18/2019 Left 1st Digit/Thumb Biopsy: Atypical Melanocytic Proliferation consistent with Early Acral Lentiginous Melanoma in situ. Margins Positive. (Not a reportable diagnosis for 2019.)

12/5/2019 Left 1st Digit Shave Biopsies: Malignant Melanoma in situ. Margins Positive.

1/15/2020 Started Aldara (treatment plan: use for ~3 months then Mohs/excision, but due to COVID could not get resection until 7/2020).

7/29/2020 Left Thumb Excision: Residual Melanoma in situ. Margins Positive. Treatment Plan: re-excision.

8/6/2020 Left Thumb Re-Excision: Atypical Lentiginous Melanocytic Proliferation at the 12-2 margin may represent the advancing edge of melanoma in situ. (8/19/2020 Plan to treat the 12-2 margin as positive with in situ; plan for re-excision).

8/20/2020 Left Thumb Re-Excision & Left Nail Plate Excision: Malignant Acral Lentiginous Melanoma with extensive melanoma in situ. Breslow 1.3mm. Margins Positive. Nail plate & bed epithelium with hemorrhage and a mild increase in melanocyte density likely represent melanoma in situ.

9/4/2020 Left thumb partial amputation & Left axillary Sentinel Lymph Node Excision: Residual Malignant Melanoma in situ. 0/3 sentinel nodes positive.
