BACKGROUND: Lymphocytoma cutis is a reactive lymphoproliferative process that histologically mimics cutaneous lymphoma. CLINICAL CASE: A 36-year-old female patient, with a dermatosis located to the face, characterized by a neoformation of oval, pink, hard, size 1.2 x 0.5 cm, asymptomatic, 6 weeks of evolution, that appeared after the insect bite. The diagnostic report of the excisional biopsy was of lymphocytoma cutis, which was confirmed by histopathology. CONCLUSIONS: Lymphocytoma cutis secondary to arthropod bites are usually localized to exposed sites, such as a solitary, self-limited erythematous nodule. The goal of treatment is to rule out a malignant process, so surgical excision is the treatment of choice. [ABSTRACT FROM AUTHOR]

The herbivory carried out by arthropods of the Curculionidae family on inflorescence of Espeletia killipii was determined experimentally through field and laboratory measurements. The samples of flowers were collected according to experimental design in two areas that present high and low anthropic alteration in the Tunjo river valley, into Chingaza Natural Park, jurisdiction of Calera-Cundinamarca. The insect feeds on the seeds causing a natural predation of this frailejon. The flowers were analyzed in the laboratory to quantify seed predation and the presence of the animal in its different stages of growth: larvae, pupae, worms and adults. The damage caused by the arthropod to the seeds of Espeletia killipii, added to the anthropogenic disturbances in the area and the increase in temperature due to climate change, can further alter the delicate balance of Espeletia killipii with the environment.
