According to the international consensus criteria (ITBCC), TB should be evaluated from the non-mucinous regions. However, some tumors also contain tumor bud-like structures within extracellular mucin pools, and the prognostic impact of these structures remains unclear. To assess this, we defined a modified tumor budding variable (TB-Muc), representing the highest number of tumor buds/bud-like structures observed in a hotspot (0.785 mm<sup>2</sup>) at the invasive margin, including extracellular mucin regions. We analyzed the prognostic significance of TB (ITBCC criteria) and TB-Muc in two CRC cohorts (N = 1876). TB-ITBCC was associated with advanced stage and lymphovascular invasion (p < 0.001) but also with shorter cancer-specific survival independent of other prognostic factors (Cohort 1: HR for high vs. low 1.99, 95 % CI 1.32–3.01, p<sub>trend</sub> = 0.0007; Cohort 2: HR 1.35, 95 % CI 0.98–1.85, p<sub>trend</sub> = 0.037).

Mutations of tuberous sclerosis genes are frequently observed in AML. Glycoprotein non-metastatic melanoma protein B (GPNMB) exhibits a low expression in most normal tissues and is transcriptionally activated by TFE3 and TFEB. Loss of TSC1/2/mTOR function paradoxically activates TFE3 and TFEB, resulting in a strong diffuse GPNMB expression. We explored the histogenesis of epithelial cysts in five AMELC cases using HMB45, Cathepsin-K, GPNMB and TSC2 immunostains. GPNMB was strongly and diffusely positive in the classic spindle cell component in all five AMLECs, but not in the cystic epithelium and associated blood vessels. Correspondingly, loss of TSC2 labeling was only seen in the classic spindle cell AML but not in the cystic epithelium and vessels. HMB45 was positive in the classic spindle cell component and not in the cystic epithelium or blood vessels. Cathepsin-K stained both spindle and epithelial components but was weaker in the epithelium. Our study demonstrates that strong diffuse expression of GPNMB correlates with loss of TSC2 expression.
