Because of the large number of different tissues making up the distal phalanx of fingers and toes, a large variety of malignant tumors can be found in and around the nail apparatus. Bowen disease is probably the most frequent nail malignancy. It is usually seen as a verrucous plaque of the nail fold and nail bed in persons above the age of 40 years. It slowly grows over a period of years or even decades before degenerating to an invasive squamous cell carcinoma. The latter may also occur primarily often as a weeping onycholysis. The next most frequent nail malignancy is ungual melanoma. Those arising from the matrix are usually pigmented and often start with a longitudinal melanonychia whereas those originating from the nail bed remain amelanotic, are often nodular and mistaken for an ingrown nail in an elderly person. The treatment of choice for in situ and early invasive subungual melanomas is generous extirpation of the nail apparatus whereas distal amputation is only indicated for advanced melanomas. In addition to these frequent nail malignancies, nail-specific carcinomas, malignant vascular and osseous tumors, other sarcomas, nail involvement in malignant systemic disorders and metastases may occur. In most cases, they cannot be diagnosed accurately on clinical grounds. Therefore, a high degree of suspicion is necessary in all isolated or single-digit proliferations that do not respond to conservative treatment.

Although allergic emergencies do not occur every day, they are as unpredictable as the course of the reaction, and require rapid treatment. Anaphylaxis is a life-threatening general reaction that usually manifests within a few minutes after a known or potential antigen contact. While sole cutaneous symptoms are not sufficient to diagnose anaphylaxis, an episode of acute bronchospasm or hypotension in rare cases may be the only symptom. Almost always two or more organ systems are affected and usually the skin and/or mucous membranes are involved. Epinephrine (adrenaline) is the most important and effective drug in the treatment of anaphylaxis. Since there is no absolute contraindication, epinephrine should be administered intramuscularly at the first signs of anaphylaxis. However, there is a gap between the international treatment guidelines and the daily practice in the treatment of acute allergic, particularly anaphylactic, reactions. This is due not least to the fact that anaphylaxis, the most severe form of allergy, is not sufficiently clear or uniformly defined. After a systemic allergic reaction, all patients should be equipped with emergency medications, appropriately instructed obtain a complete allergy work-up.
