Advances in the treatment of aplastic anemia (AA) have led to the long-term survival of nontransplanted AA patients; however, the issue of subsequent hematological clonal disorders has been raised as some AA patients treated with immunosuppressive therapy or granulocyte-colony stimulating factor (G-CSF) went on to develop myelodysplastic syndromes (MDS) and/or acute myeloid leukemia (AML) with the frequent presentation of monosomy 7. We report a case of AA progressing to overt MDS/AML following 11 years of treatment that included immunosuppressive therapy and G-CSF. The patient's MDS/AML proved refractory to therapy including myeloablative treatment with allogenic peripheral blood stem cell transplantation. Earlier reports and the present case strongly suggest that there is no recurrent chromosomal aberration other than monosomy 7 in cases of AA that progress to MDS/AML. To our knowledge, ours is the first reported case of a t(3;5)(p25;q31) among AA patients that have progressed to MDS/AML.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

Cellular Adaptation IV: Dysplasia and Metaplasia

DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...
Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
