Fibrodysplasia ossificans progressiva, “Stone Man Syndrome”
Fibrodysplasia ossificans progressiva (FOP) is a progressive genetic disorder that turns soft tissues into bone over time.
A large family simply known as the “blue people” lived in the hills around Troublesome Creek in Kentucky until the 1960s. Read the rest of this entry
Epidermodysplasia verruciformis is an extremely rare disorder that makes people prone to widespread human papillomavirus (HPV) infection. This infection causes scaly macules and papules (cutaneous squamous cell carcinomas) to grow on the hands, feet, and even face.

The Dragon Blood Tree (Dracaena cinnabari)is the most famous and distinctive plant of the island of Socotra. It has a unique and strange appearance. This evergreen species is named after its dark red resin, which is known as “Dragon’s Blood”.
The dragon’s blood tree usually produces its flowers around February, though flowering does vary with location. The flowers tend to grow at the end of the branches. The flowers have inflorescences, and they bear small clusters of fragrant, white or green flowers.
The fruits take five months to completely mature. The fruits are described as a fleshy berry, which changes from green to black as it gradually ripens.
This genetic disorder is as rare as it is severe. The classic form of the disease, called Hutchinson-Gilford Progeria, causes accelerated aging.
Hypertrichosis is also called “Werewolf Syndrome”. It affects as few as one in abillion people; and in fact, only 50 cases have been documented since the Middle Ages.
Some times mutation occurs and both eyes of a human can attain different colors. This is called Heterochromia Iridum. It usually occurs in iris but can also happen due to relative excess or lack of melanin pigment or may be inherited.
Most of us are aware of the eight basic blood types (A, AB, B, and O—each of which can be positive or negative), there are currently 35 known blood group systems according ISBT with millions of variations in each system. Blood that doesn’t fall into the ABO system is considered rare, and those who have such blood may find it challenging to locate a compatible donor when in need of a transfusion.
