Summary

Here is an overview of all rare diseases (Selsuche) that begin with a letter after which they were joined in the text.

The list system is programmed to always sort by the letter M, N, O, P, R, S, T, U, V, W, X and Z. Because these are complex medical contexts, not all entities are fully defined for each letter (e.g., a neoplasm may have more than one description or sickle cell disease may have multiple letters).

### M: Malignant neoplasm of the central nervous system
1. Malignant astrocytoma
2. Malignant fibrous histiocytoma
3. Malignant glioma
4. Malignant oligodendroglioma
5. Mantle cell lymphoma
6. Refractory mantle cell lymphoma
7. Mantle cell lymphoma stage II
8. Mantle cell lymphoma stage III
9. Mantle cell lymphoma stage IV
10. Malignant glioma (Table also shows other associated but usually less prominent M syndromes such as mantle cell lymphoma, which are often separate or in cluster "M")
*Note: There are several variants of "malignant glioma" (e.g. leukoblastoma is often in the nucleus of neoblastomas, but is summarized here under "M" in the list system).*

### N: Rare diseases starting with the letter N
1. Narcolepsy
2. Nasopharyngeal carcinoma
3. Necrotizing myositis
4. Neonatal alloimmune thrombocytopenia
5. Nephroblastoma

### O: Rare diseases that begin with the letter O
1. Obliterative bronchiolitis
2. Esophageal atresia
3. Esophageal carcinoma
4. Optic glioma
5. Ornithine transcarbamoylase deficiency
6. Oropharyngeal squamous cell carcinoma
7. Osteochondrodysplasia
8. Osteogenesis imperfecta
9. Osteosarcoma
10. Osteosarcoma with metastases
11. Osteosarcoma recurrence

### P: Rare diseases starting with the letter P
1. Paraneoplastic neurological syndrome
2. Paroxysmal nocturnal hemoglobinuria
3. Pelizaeus-Merzbacher disease
4. Pemphigoid
5. Pemphigus
6. Penile cancer
7. Plasma cell myeloma
8. Plasma cell myeloma refractory
9. Plasma cell myeloma recurrence
10. Squamous cell carcinoma of the oral cavity
11. Squamous cell carcinoma of the vulva
12. Squamous cell carcinoma of the anus
13. Squamous cell carcinoma of the hypopharynx
14. Squamous cell carcinoma of the larynx
15. Pleomorphic liposarcoma

### R: Rare diseases starting with the letter R
1. Retinitis pigmentosa
2. Retinoblastoma
3. Rett syndrome
4. Recurrence of acute lymphoblastic leukemia
5. Recurrence of acute myeloid leukemia
6. Recurrent medulloblastoma
7. Recurrent neuroblastoma
8. Rhabdoid tumor
9. Rhabdomyosarcoma
10. Rhabdomyosarcoma recurrence
11. Richter syndrome
12. Giant cell arteritis
13. Giant cell tumor of the tendon sheath
14. Rosai-Dorfman syndrome
15. Round cell liposarcoma

### S: Rare diseases starting with the letter S
1. SAPHO syndrome
2. Sarcoidosis
3. Sarcoma
4. Mucosal pemphigoid
5. Severe myoclonic epilepsy of childhood
6. Shprintzen-Goldberg syndrome
7. Sickle cell anemia
8. Sickle cell disease
9. Sjoegren syndrome
10. Solitary fibrous tumor
11. Salivary gland carcinoma
12. Spinal muscular atrophy
13. Stargardt syndrome
14. Stevens-Johnson syndrome
15. Still's disease
16. Urea cycle disorder
17. Fragile X chromosome syndrome
18. Isodicentric chromosome syndrome 15
19. Synovial sarcoma
20. Synovial sarcoma with metastases
21. Sickle cell disease (Table also shows other variants in Selsuche such as "S", but here in point S "sickle cell disease" is the main name. Since the Selsuche begins "S", this disease is explicitly recorded in point S, although it also often has "S".
22. Sijerger syndrome
23. Sjoegren syndrome
24. Solitary fibrous tumor
25. Schwaiger-Buch syndrome
26. Severe myoclonic epilepsy of childhood
27. Synovial sarcoma
28. Synovial sarcoma with metastasis
