Orbital extension of supraorbital angiolymphoid hyperplasia with eosinophilia.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare clinicopathologic entity that shares both clinical and histopathological features with Kimura disease. Although they were once considered as different stages of the same disease, they are now known to represent separate entities. ALHE is a condition that causes swellings in the head and neck region affecting muscular arteries and is benign in nature.1 Orbital involvement is unusual. Diagnosis of ALHE is frequently confused with malignant tumour until biopsy is done.4 We present here a young female with unilateral, painless and slowly progressive swelling on the inner and upper aspect of her left orbit, who was diagnosed as a case of ALHE with orbital involvement on the basis of CT scan and excisional biopsy. Regular follow up was performed and no evidence of recurrence was found.

Phalange metastasis from carcinoma of alveolus.

Metastatic involvement of a phalanx by head and neck cancers is rare. We report a case of a 66-year-old man with squamous cell carcinoma of the alveolus who had no residual disease or local recurrence after treatment but presented with metastasis to the middle phalanx of the middle finger.

Chloroplast inheritance and DNA variation in sweet, sour, and ground cherry.

Sour cherry (Prunus cerasus L.) is an allotetraploid and both sweet cherry (P avium L.) and ground cherry (P. fruticosa Pall.) are the proposed progenitor species. The study investigated the maternal species origin(s) of sour cherry using chloroplast DNA (cpDNA) markers and a diverse set of 22 sweet, 25 sour, and 7 ground cherry selections. Two cpDNA restriction fragment length polymorphisms (RFLPs) and one polymerase chain reaction (PCR) fragment length polymorphism were identified among the 54 selections. The three polymorphisms considered together resolved four haplotypes. Analysis of sour cherry progeny indicated that the chloroplast genome is maternally inherited and therefore appropriate to use in determining maternal phylogenetic relationships. Ground cherry was found more likely than sweet cherry to be the maternal progenitor species of sour cherry since 23 of 25 of the sour cherry selections had the most prevalent ground cherry haplotype. However, the other two sour cherry selections tested had the most prevalent sweet cherry haplotype and a wild French sweet cherry selection had the most prevalent ground cherry haplotype. The results underscore the importance of using diverse Prunus germplasm to investigate phylogenetic relationships.
