Beau's lines and pyogenic granulomas following hand trauma.
We report two cases of trauma-induced Beau's lines accompanied by pyogenic granulomas of the proximal nail folds of the affected fingers. The preceding trauma was not directly to the nail matrix but was more proximal, on the palm in one case and the arm in the other. The simultaneous occurrence of Beau's lines and pyogenic granulomas following trauma has not been reported previously in the literature.

Seizures and dermatitis after exposure to caprolactam.
A 22-year-old man was initially seen with dermatitis, fever, and seizures after three days of occupational exposure to caprolactam, a nylon fiber precursor. A comprehensive neurological investigation showed no organic CNS abnormalities. Although caprolactam has been shown to induce convulsive disorders in experimental animals, to our knowledge, there are no reports of caprolactam-induced seizures in man. The coincidence of typical skin lesions with otherwise unexplained grand mal seizures in this strongly suggests that caprolactam was the cause.
