## 해설

Worsening dysmenorrhea with heavy bleeding and a uniformly enlarged, boggy, tender uterus in a parous woman in her late 30s is the classic picture of adenomyosis, in which endometrial glands grow within the myometrium. Endometriosis typically adds dyspareunia, painful defecation, or infertility and does not enlarge the uterus itself. Fibroids enlarge the uterus as firm, irregular masses, and pelvic inflammatory disease causes cervical motion tenderness.

## 심화 해설

Clinical picture and why it points to adenomyosis

This patient’s presentation combines three findings that fit the classic adenomyosis pattern: progressively worsening dysmenorrhea over several years, heavy menstrual bleeding severe enough to soak a pad every 2 hours, and a uterus that feels uniformly enlarged, soft, and tender on bimanual examination. In adenomyosis, endometrial glands and stroma invade the uterine myometrium, producing a diffusely thickened, boggy uterine wall rather than a discrete mass [1][4]. The uterus itself enlarges because the ectopic endometrial tissue within the muscle layer responds to hormonal stimulation, causing surrounding myometrial hypertrophy, inflammation, and fibrosis [3]. Heavy menstrual bleeding is the most commonly reported symptom of adenomyosis, and the bleeding arises from increased endometrial surface area, altered uterine contractility, and local inflammatory changes within the myometrium [1][2].

Why the other options are less likely

Endometriosis is defined by endometrial tissue outside the uterus, most often on pelvic peritoneum, ovaries, or the rectovaginal septum [1]. It frequently causes dyspareunia, painful defecation, or infertility, and it does not by itself produce a uniformly enlarged, boggy uterus. This patient has no pain with intercourse or bowel movements, which makes endometriosis less consistent with the findings. Uterine leiomyomas, or fibroids, can also cause heavy bleeding and an enlarged uterus, but the enlargement is typically described as firm and irregular because fibroids are discrete smooth-muscle tumors. The bimanual finding of a soft, uniformly enlarged uterus without discrete masses argues against leiomyoma. Chronic pelvic inflammatory disease usually presents with cervical motion tenderness, adnexal tenderness, or fever, none of which are present here.

| Condition | Uterine size and consistency | Key distinguishing symptoms | Bimanual findings |
| --- | --- | --- | --- |
| Adenomyosis | Uniformly enlarged, soft, boggy | Worsening dysmenorrhea, heavy menstrual bleeding | Diffusely tender uterus, no discrete mass |
| Endometriosis | Usually normal size | Dyspareunia, painful defecation, infertility | Nodularity or tenderness in cul-de-sac, not uterine enlargement |
| Uterine leiomyoma | Enlarged, firm, irregular | Heavy bleeding, pressure symptoms | Discrete firm masses |
| Chronic pelvic inflammatory disease | Usually normal size | Pelvic pain, fever, abnormal discharge | Cervical motion tenderness, adnexal tenderness |

Risk factors and diagnostic context

This patient is parous and in her late 30s, which aligns with known risk factors for adenomyosis. Increasing age and parity are consistently associated with a higher likelihood of developing the condition [1]. Adenomyosis is most often diagnosed in patients from 40 to 50 years of age, but symptomatic disease can present earlier, especially in parous women [1]. The negative pregnancy test is important because it excludes pregnancy-related causes of an enlarged, soft uterus, such as early pregnancy or molar pregnancy, before considering structural uterine pathology.

How the pathophysiology explains the physical findings

The soft, boggy consistency reflects the diffuse infiltration of endometrial tissue into the myometrium rather than a well-circumscribed tumor. The tenderness is caused by inflammation, fibrosis, and neuroangiogenesis within the affected uterine wall [3]. Because the ectopic endometrial glands are embedded within the myometrium, the uterus enlarges symmetrically, and the enlargement is tender on palpation, which is a key feature distinguishing adenomyosis from fibroids. The heavy bleeding and worsening dysmenorrhea are both driven by the same underlying process: ectopic endometrial tissue within the muscle layer bleeds and induces local inflammation during each menstrual cycle, leading to painful uterine contractions and increased menstrual flow [1][3].

Diagnostic confirmation and clinical application

Although the diagnosis of adenomyosis was historically made only after hysterectomy, current guidelines support noninvasive diagnosis using transvaginal sonography or magnetic resonance imaging [2][4]. Imaging can demonstrate a diffusely thickened myometrium, myometrial cysts, or an indistinct endometrial–myometrial junction. Key point! A uniformly enlarged, soft, tender uterus in a parous woman with heavy bleeding and progressive dysmenorrhea should prompt imaging for adenomyosis rather than assuming fibroids, because the management and counseling differ. Watch out! Adenomyosis and endometriosis can coexist, so the absence of endometriosis symptoms does not completely rule out endometriosis, but the dominant clinical picture here is adenomyosis [1].References (research sources)

## 임상 시나리오

Adenomyosis RecognitionClassic triad in a parous woman
Suspect adenomyosis when a parous woman in her late 30s reports worsening dysmenorrhea and heavy menstrual bleeding, and bimanual exam reveals a uniformly enlarged, soft, tender uterus with no discrete masses.

Heavy bleeding is the most common symptom, driven by increased endometrial surface area, altered contractility, and local inflammation within the myometrium. Bleeding severe enough to soak a pad every 2 hours warrants prompt evaluation.

CautionDo not confuse adenomyosis with leiomyoma: fibroids feel firm and irregular, not diffusely boggy. Absence of cervical motion tenderness and fever makes pelvic inflammatory disease unlikely.

## 핵심 개념

- **Adenomyosis** — Endometrial glands and stroma invade the myometrium, causing diffuse uterine enlargement, heavy bleeding, and worsening dysmenorrhea.
- **Boggy uterus** — A soft, uniformly enlarged, tender uterus on bimanual exam, characteristic of adenomyosis rather than fibroids.
- **Endometriosis** — Endometrial tissue outside the uterus, often causing dyspareunia, painful defecation, or infertility without diffuse uterine enlargement.
- **Uterine leiomyoma** — Benign smooth muscle tumor that enlarges the uterus as firm, irregular discrete masses.
- **Cervical motion tenderness** — Pain elicited by moving the cervix during bimanual exam, a classic sign of pelvic inflammatory disease.
