Meningeal melanomatosis is an extra-axial well-encapsulated malignant tumour with diffuse meningeal growth and dark coloration (due to high melanin contents), while meningeal melanocytoma is the focalized benign variant. Melanocytic lesions may be secondary to melanoma or be histologically benign, however, their diffuse nature makes them impossible to cure. Melanocytosis is a diffuse tumour that can form solitary extra-axial tumours, which invades the parenchyma and presents signs of malignancy with increased mitosis and Ki67, observed in 1 to 6% of immunopathological exams. Melanoma of the leptomeninges, presents signs of malignancy with anaplastic cells, which cluster in fascicles of melanin in the cytoplasm, with more than 3 atypical mitoses per field and Ki67 presenting in more than 6% of the immunopathological fields analysed. ⋯ Benign melanocytic neoplasms of the central nervous system must be treated aggressively in the early phases with strict follow-up to avoid progression to advanced phases that do not respond to any treatment method. Unfortunately, the prognosis for malignant melanocytic lesions is very poor irrespective of the method of treatment given.

Pancreatic diseases such as cancer, idiopathic recurrent pancreatitis, and chronic pancreatitis, can cause pain that is difficult to control. Pain is one of the most debilitating symptoms and demands increasing doses of analgesics and narcotics, as well as the number of hospital admissions, with a direct implication in the costs of medical treatments. ⋯ This technique showed that both patients obtained satisfactory pain relief, with significant improvements in general symptomatology and the stopping of almost all analgesic medication. The authors suggest that celiac ganglion block must be considered, and implemented early before the usual complications, such as a consumption syndrome that is frequent in paediatric patients with chronic pancreatitis.
