Connective tissue diseases, also connective tissue disorders, are infrequently seen by pathologists.
They may be very important in the context of forensic pathology, as they may be an explanation for multiple fractures, which may be seen in child abuse.
Specific entities
Mixed connective tissue disease
- Abbreviated MCTD.
General
- A wastebasket diagnosis in rheumatology.
Usually has some features of:[1]
- Systemic lupus erythematosus.
- Systemic sclerosis.
- Polymyositis.
Ehlers-Danlos syndrome
Main article: Ehlers-Danlos syndrome
Marfan syndrome
Main article: Marfan syndrome
Osteogenesis imperfecta
- Abbreviated OI.
General
- Rare.
- Numerous subtypes - mild-to-severe symptoms/survival.
- May be misdiagnosed as child abuse.[2]
Clinical:
- +/-Blue sclerae.[3]
- Multiple fractures.
General
- Classic - tibial bowing (saber shins).[4]
Microscopic
Features:[4]
- Abundant plump osteoblasts (infants only).
- Paucity of bony matrix.
- Premature calcification of osteoid.
