Pubertal Delay Secondary to Hashimoto's Disease in the Hypothyroid Phase: About a Case in the Internal Medicine Department of the Gabriel Touré University Hospital in Bamako, Mali

Introduction: Pubertal delay is defined by the absence of development of secondary sexual characteristics beyond the age of 13 in girls or 14 years in boys. In children of puberty age, delayed puberty is common in long-standing, untreated hypothyroidism. We report a case of delayed puberty revealed by Hashimoto's disease in the hypothyroid phase diagnosed in the Internal Medicine department of the Gabriel Touré University Hospital in Bamako, Mali. Observation: This was a female patient, aged 20 years old, without any particular medico-surgical ATCD or notion of taking medication, who had consulted at the end of 2021, in the Internal Medicine department of the University Hospital Gabriel Touré from Bamako for primary amenorrhea and delayed puberty. At the end of the clinical and paraclinical examination, a hypometabolism syndrome and pubertal delay were noted. On an evolutionary level, development of secondary sexual characteristics (From T1 to T3, and appearance of menstruation) after one year of treatment. Conclusion: Delayed puberty may be the consequence of hypothyroidism. Opotherapy with L Thyroxine helps restore normal pubertal development.
