A mole with a honeycomb pattern An individual presents with a flat pigmented mole about the relative back of the shoulder. Case presentation A 48-year-old man had a longstanding mole on the trunk of his remaining shoulder . The mole measured 5 mm in diameter and had gradually increased in size. Dermoscopy revealed a darkish reticulate network with a honeycomb design that faded at the periphery of the mole . Pores and skin biopsy showed an epidermis with prominent narrow and elongated rete ridges. The rete ridges were pigmented and contained increased numbers of melanocytes deeply. In the underlying dermis there have been many benign naevus cells which lacked pigment .‘Near infrared spectroscopy can be a scientific tool which has helped us understand the differences between legitimate and counterfeit drugs, also those which look exactly the same to the naked vision,’ Professor Moffat said. Along with being able to recognize counterfeit from authentic tablets, the chemical details supplied by NIR spectroscopy assists identify the most likely origin of the tablet. Thus police agencies obtain precious information about the laboratories making counterfeit medicines. Today’s paper was presented at the 13th International Conference on Near Infrared Spectroscopy in Umea, Sweden.
