RESUMO
Colorectal cancers rarely present with bone metastases. Regular postoperative monitoring after resection by conventional imaging techniques and carcinoembryonic antigen levels aids physicians in identifying such tumor recurrences. However, some recurrences might elude detection by bone scan, computed tomography, and magnetic resonance imaging, and newer tests such as immunoscintigraphy using radioimmune-tagged monoclonal antibodies may be more diagnostic. Here we report a case, presenting with delayed recurrence at a rare bony site, in which application of immunoscintigraphy helped in the definitive detection of the tumor recurrence.

Basal plasma cortisol levels in 12 controls and 60 patients with different types of leprosy were within normal limits. They were significantly lower in multibacillary leprosy patients; this abnormality might be due to long standing stress leading to adrenal exhaustion. The plasma cortisol level significantly increased after the ACTH (Synacthen) stimulation test in all of the varieties of leprosy tested, which suggests that the adrenal reserve is maintained in such cases.

In adults, lichen planus (LP) is relatively more common than in children. Among 222 cases of LP, there were 25 (11.2%) children in our study. The majority of the cases were females in the age group of 8-14; the youngest child was 3 years old. Papular and linear types of LP were common in children. There was no familial history of LP in any of the cases. The patients with classic LP lesions responded well to dapsone therapy. This study supports the suggestion of Ramsay and Hurley that childhood LP is more common in the tropics.
