Immunoblotting confirmed RAS elevation, along with upregulation/phosphorylation of PI3K, AKT, and CREB. Blocking RAS signaling in MB21D2-expressing cells by manumycin significantly reduced cell growth and survival. Our study thus defined RAS signaling-dependent pro-oncogenic roles for MB21D2 overexpression and Q311E MB21D2 expression in HNSCC development. Acral lentiginous melanoma (ALM) carries one of the worst prognoses among other subtypes. This malignant tumor is found on the distal limbs and is usually detected at late stages. Hereby, the authors present their experience on this melanoma subtype. A retrospective study was conducted. Data were extracted from patients' medical records and from phone interviews. A total of 43 patients were included in the study. The main signs and symptoms disclosed by the patients were bleeding (41.9%), size greater than 6mm (41.9%), change in size (37.2%), change in shape (30.2%), rise above the surface of the skin (27.9%), change in color (20.9%), irregular borders (16.3%), and inflammation (16.3%). The first healthcare professional consulted was a general practitioner or a dermatologist in the majority of cases (88.3%). Only 44.2% of the patients were sent by their first physician for a biopsy, whereas 30.3% were sent by the 2nd physician. 14 patients underwent biopsy within 1month from the first appointment with a physician, while 20 patients within 3months and 9 patients within 6months. Only 7 patients sought medical attention in the first 3months; 21 patients sought medical care between 3months and one year from the appearance of the lesion, while the remaining 15 patients waited more than a year. One of the major issues found in ALM is represented by the diagnostic delay; this may be due to either the patients or
