[Anaphylaxis due to Solanum betaceum].

Tree tomato (Solanum betaceum or Cyphomandra betaceae) or tamarillo belongs to the Solanaceae family and is widely consumed in Latin American countries. We report the case of a 43-year-old male from Ecuador who suffered two systemic anaphylaxis after drinking tamarillo juice, with previous tolerance to tamarillo on several occasions. Allergology study showed positivity in prick-prick to tamarillo peel and pulp and negativity to other types. SDS-PAGE immunoblotting with peel-pulp and Western Blot showed multiple bands between 14-75 kDa in tamarillo peel and 11-75 kDa in pulp. ELISA inhibition showed that tamarillo only inhibited itself. Given the results and tolerance to other types of tomato, we believe that the causative protein could be selective, so we report the first case of primary sensitivity to Solanum betaceum (tamarillo).
